BACKGROUND OF THE PRESENT INVENTION 
     Field of Invention 
     The present invention relates to the field of microwave-doppler detection and, in particular, to a microwave-doppler detecting module and device thereof. 
     Description of Related Arts 
     Microwave detection technologies based on Doppler Effect, are utilized as a critical key in detecting and relating humans and objects and have a unique advantage among the behavior detection and existence detection technologies. It is able to detect moving object without invading individual privacy. Therefore, such technology has a wide-ranging application prospect. 
     Conventional microwave detection modules, based on the structures of the radiation source, can mainly be divided into microwave detection modules of columnar radiation source structure and microwave detection modules of flat radiation source structure. More specifically, referring to  FIGS. 1A and 1 , the structural principles of conventional microwave detection module  10 P of columnar radiation source structure and microwave detection module  20 P of flat radiation source structure are respectively illustrated. In which, the microwave detection module  10 P of columnar radiation source structure comprises a columnar radiation source  11 P and a reference ground surface  12 P, wherein the reference ground surface  12 P has a radiating aperture  121 P arranged thereon, wherein the columnar radiation source  11 P perpendicularly penetrates the reference ground surface  12 P through the radiating aperture  121 P and a radiating clearance  1211 P is provided between the radiating aperture  121 P and the reference ground surface  12 P, so that when the columnar radiation source IP is fed, the columnar radiation source  11 P can be coupled with the reference ground surface  12 P to form a radiation space  100 P from the radiating clearance  1211 P with the columnar radiation source  11 P as the central axis, wherein the radiation space  100 P is the coverage area of the electromagnetic wave radiated by the microwave detection module  10 P of columnar radiation source structure, wherein the radiation space  100 P is respectively sunken from the central axis at the two ends of the columnar radiation source  11 P, rendering detection dead zones. It is understandable that, in actual utilization, such as a vertical detecting application, when the microwave detection module  10 P of columnar radiation source structure is mounted on a place such as a suspended ceiling, regular ceiling, shed ceiling, and etc., and is utilized from a vertical direction to perpendicularly detecting downward, the mounting position of the microwave detection module  10 P of columnar radiation source structure is usually lowered for reducing or avoiding detection dead zone of the corresponding radiation space  100 P from occurring in the space between the ground and the microwave detection module  10 P of columnar radiation source structure. In other words, because the microwave detection module  10 P of columnar radiation source structure has a detection dead zone, the detecting distance of the microwave detection module  10 P of columnar radiation source structure in real utilization is way smaller than the maximum size of the corresponding radiation space  100 P in the central axial direction. That is the detecting distance of the microwave detection module  10 P of columnar radiation source structure in real utilization is much smaller than the detecting distance according to the scale of the gain thereof. The gain of the conventional microwave detection module OP of columnar radiation source structure, which is usually about 2 dB, further limits the application of the conventional microwave detection module  10 P of columnar radiation source structure in the field of microwave-doppler detection. 
     Referring to  FIG. 1B , the structure and principle of the microwave detection module  20 P of flat radiation source structure are illustrated, wherein the microwave detection module  20 P of flat radiation source structure includes a flat panel radiation source  21 P and a reference ground surface  22 P, wherein the flat panel radiation source  21 P and the reference ground surface  22 P are spacingly arranged and parallel to each other, while a radiating clearance  23 P is defined and provided between the flat panel radiation source  21 P and the reference ground surface  22 P. It is understandable that because, structurally, the columnar radiation source  11 P of the microwave detection module  10 P of columnar radiation source structure is perpendicular to the reference ground surface  12 P, comparing to the microwave detection module  20 P of the flat radiation source structure that is close to a flat plate structure, the microwave detection module  10 P of columnar radiation source structure is likely to occupy a larger mounting space in an actual installation. As a result, under the current aesthetic trend of pursuing compact and simple appearance, the microwave detection module of flat radiation source structure is more enjoyable and appreciable to its advantages of small volume and relative stabilization. 
     Nevertheless, in some application scenarios, the microwave detection module  10 P of columnar radiation source structure is more advantageous than the microwave detection module  20 P of flat radiation source structure. For example, referring to  FIG. 2 , the application of the microwave detection module  10 P of columnar radiation source structure utilized in a LED light board  30 P is illustrated, wherein the LED light board  30 P has a plurality of LED lights  31 P arranged on one side thereof, so as to create a lighting side on the side of the LED light board  30 P. It is understandable that, in order to control the illumination of the LED light board  30 P based on human activity, conventional microwave detection module is utilized on such LED light board  30 P and, according to actual application, effective electromagnetic wave detecting signal should be radiated in the space corresponding to the lighting side of the LED light board  30 P. Because current LED light boards  30 P are usually made of electric conductive aluminum sheet, in order to avoid the shielding effect of the electric conductive LED light board  30 P to the electromagnetic wave detecting signal and from the perspective of the stability of human activity detecting, ideally, the microwave detection module as a human activity detecting component should be disposed on the illumination side of the LED light board  30 P. Nevertheless, whether the microwave detection module  10 P of columnar radiation source structure or the microwave detection module  20 P of flat radiation source structure is utilized, because the corresponding reference ground surface  12 P and the minimum value of the area size of the reference ground surface  22 P are restricted, the mounting of the microwave detection module  10 P of columnar radiation source structure or the microwave detection module  20 P of flat radiation source structure on the illumination side of the LED light board  30 P will inevitably occupy the mounting sites of part of the LED lights  31 P or shade part of the LED lights  31 P, rendering dark zone of the light emitted by the LED light board  30 P. 
     Hence, in order to achieve the illumination of the LED light board  30 P based on the control of human activity, conventionally it is mainly based on the arrangement from affecting the LED lights  31 P. A through hole  32 P is formed in the LED light board  30 P. Besides, the columnar radiation source  11 P of the microwave detection module  10 P of columnar radiation source structure is extended from the side of the LED light board  30 P opposite to the illumination side through the through hole  32 P to pass through the LED light board  30 P to the illumination side of the LED light board  30 P, so as to conceal the reference ground surface  12 P of the microwave detection module  10 P of columnar radiation source structure on the side of the LED light board  30 P opposite to the illumination side. Therefore, the mounting of the microwave detection module  10 P of columnar radiation source structure on the LED light board  30 P can avoid occupying the sites of part of the LED lights  31 P or shading part of the LED lights  31 P, so as to maintain the evenness and uniformity of the light emitted from the LED light board  30 P. Nonetheless, in real utilization, due to the limits of the maximum value of the size of the through hole  32 P and the minimum value of the thickness of the LED light board  30 P, the coupling between the reference ground surface  12 P and the columnar radiation source  11 P of the microwave detection module  10 P of columnar radiation source structure will be blocked by the LED light board  30 P. In other words, the corresponding radiation space  100 P on the illumination side of the LED light board  30  will be reduced due to the shielding and reflex action of the LED light board  30 P. As a result, the stability of the human activity detection of the microwave detection module  10 P of columnar radiation source structure utilized on the LED light board  30 P is not ideal. In addition, because of the reflex action of the LED light board  30 P and the directivity of the bidirectional radiation of the microwave detection module  10 P of columnar radiation source structure, the corresponding radiation space  100 P at the side opposite to the illumination side of the LED light board  30 P will be enhanced. In other words, the radiating energy of the microwave detection module  10 P of columnar radiation source structure on the side opposite to the illumination side of the LED light board  30 P will be enhanced. As a result, when there is metal object, such as the metal shell of the LED light board  30 P, the metal pipeline in the suspended ceiling space, and etc., presenting in the corresponding space of the side opposite to the illumination side of the LED light board  30 P, the microwave detection module  10 P of columnar radiation source structure is likely to wrongly detect active object due to self-excitation, which therefore affects the experience of the smart control of the LED light board  30 P based on detecting human activity. 
     In other words, contrasting to the microwave detection module  20 P of flat radiation source structure, the microwave detection module  10 P of columnar radiation source structure can achieve the activity detecting to the space outside of the shielded space through a conceal mounting manner that extends the columnar radiation source  11 P from a shielded space corresponding to one side of a metal plate through a through hole to the space outside of the shielded space corresponding to the other side of the metal plate. Unfortunately, its detecting stability is not good enough and it has detection dead zone.

     The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

Therefore, the above-mentioned terminologies shall not be interpreted as confine to the present invention. 
     It is understandable that the term “a” should be understood as “at least one” or “one or more”. In other words, in one embodiment, the number of an element can be one and in other embodiment the number of the element can be greater than one. The term “a” is not construed as a limitation of quantity. 
     Referring to  FIG. 3  of the drawings, a 3D structure of a microwave-doppler detecting module  10  according to a preferred embodiment of the present invention is illustrated, wherein the microwave-doppler detecting module  10  comprises at least one pair of antithetical dipoles  11 , wherein the pair of the antithetical dipoles  11  comprises a first radiating source pole  111  and a second radiating source pole  112 , wherein the second radiating source pole  112  has a second feed end  1121  while the first radiating source pole  111  has a first feed end  1111 , wherein the second feed end  1121  and the first feed end  1111  are close to each other, wherein the second radiating source pole  112  is a conductor extended from the second feed end  1121  as an end, while the first radiating source pole  111  is a conductor extended from the first feed end  1111  as an end. In which, the first radiating source pole  111  and the second radiating source pole  112  are configured to be adapted for being fed by the same source at the first feed end  1111  and the second feed end  1121  respectively, wherein the second feed end  1121  and the first feed end  1111  are close to each other and satisfy that a distance between the second feed end  1121  and the first feed end  1111  is smaller than or equal to λ/32, wherein λ is the wavelength parameter corresponding to the feed signal frequency. Accordingly, when the first radiating source pole  111  and the second radiating source pole  112  are fed by the same source at the first feed end  1111  and the second feed end  1121  respectively, the first radiating source pole  111  from the first feed end  1111  along the first radiating source pole  111  is correspondingly coupled to the corresponding positions of the second feed end  1121  of the second radiating source pole  112  along the second radiating source pole  112 , so as to form the antithetical coupling arrangement between the first radiating source pole  111  and the second radiating source pole  112 . 
     It is worth mentioning that, based on the antithetical coupling between the first radiating source pole  111  and the second radiating source pole  112 , a size requirement for the second radiating source pole  112  and the first radiating source pole  111  to couple with each other can be reduced. Specifically, the second radiating source pole  112  and the first radiating source pole  111  are configured to satisfy that the wire lengths respectively from the second feed end  1121  and the first feed end  1111  are greater than or equal to λ/16. In other words, the first radiating source pole  111  is configured to satisfy that the first feed end  1111  and the end opposite to the first feed end  1111  has a wire length therebetween greater than or equal to λ/16, wherein the second radiating source pole  112  is configured to satisfy that the second feed end  1121  and the end opposite to the second feed end  1121  has a wire length therebetween greater than or equal to λ/16. In other words, the first radiating source pole  111  and the second radiating source pole  112  allow a minimum wire length of λ/16 from the first feed end  1111  and the second feed end  1121 . 
     Preferably, the distance between the second feed end  1121  and the first feed end  1111  is close to λ/128, so as to reduce the depletion in the coupling between the first radiating source pole  111  and the second radiating source pole  112  and correspondingly enhance the gain of the microwave-doppler detecting module  10 . 
     In particular, according to the disclosure of the preferred embodiment of the present invention, the microwave-doppler detecting module  10  is embodied as example to feedably connect the first radiating source pole  111  and the second radiating source pole  112  at the first feed end  1111  and the second feed end  1121  respectively with different poles of the same excitation signal feed source so as to be fed by the same source. 
     Specifically, according to this embodiment of the present invention, the first radiating source pole  111  is feedably connected with the feeder pole of the excitation signal feed source at the first feed end  1111  and the second radiating source pole  112  is electrically connected with the grounding pole of the excitation signal feed source at the second feed end  1121  so as to be fed by the same source of the excitation signal feed source with the first radiating source pole  111 , wherein the first radiating source pole  111  from the first feed end  1111  along the first radiating source pole  111  is correspondingly coupled with the corresponding positions of the second radiating source pole  112  from the second feed end  1121  along the second radiating source pole  112  so as to form and create a radiation space  100 , wherein the radiation space  100  is the coverage area of the electromagnetic wave radiated by the microwave-doppler detecting module  10 . In which, because the first radiating source pole  111  from the first feed end  1111  along the first radiating source pole  111  is correspondingly coupled with the corresponding positions of the second radiating source pole  112  from the second feed end  1121  along the second radiating source pole  112 , so that the radiation space  100  formed through the antithetical coupling manner can protrude in a radial direction of the connection of the first feed end  1111  and the second feed end  1121  so as to avoid forming a detection dead zone in such direction, which facilitates to enhance the detecting stability and applicability of the microwave-doppler detecting module  10 . 
     Further, the microwave-doppler detecting module  10  has an electromagnetic reflecting surface  12 , wherein the first radiating source pole  111  and the second radiating source pole  112  are arranged spacingly to the electromagnetic reflecting surface  12  in the space corresponding to the electromagnetic reflecting surface  12 , so as to utilize the reflection characteristic of the electromagnetic reflecting surface  12  relative to the electromagnetic wave to form the directional radiation characteristic of the microwave-doppler detecting module  10 . Therefore, the microwave-doppler detecting module  10  is suitable for sensing and detecting object activity in the directional space and facilitates to avoid the microwave-doppler detecting module  10  from self-activating, which enhances the anti-interference ability of the microwave-doppler detecting module  10 . 
     In particular, the electromagnetic reflecting surface  12  is configured to satisfy that the distance thereto from the midpoint of the connection of the first feed end  1111  and the second feed end  1121  is greater than or equal to λ/32 and smaller than or equal to λ/2 and, preferably, close to λ/4. Therefore, the reflex action of the electromagnetic reflecting surface  12  for the radiation in the direction from the first radiating source pole  111  and the second radiating source pole  112  to the electromagnetic reflecting surface  12  can be enhanced, so as to facilitate to extent the detecting distance of the microwave-doppler detecting module  10 . 
     Further, based on the structural relations that the first feed end  1111  and the second feed end  1121  close to each other, the first radiating source pole  111  is extended from the first feed end  1111  as an end, and the second radiating source pole  112  is extended from the second feed end  1121  as an end, the first radiating source pole  111  and the second radiating source pole are able to be coupled with each other in an antithetical coupling manner. Correspondingly, the wire length of the second radiating source pole  112  is corresponding to the wire length of the first radiating source pole  111 , so that the second radiating source pole  112  is able to be free from the limit of the reference plane of a restricted minimum area, which means that the wire length of the second radiating source pole  112  corresponding to it of the first radiating source pole  111  may have various structural implementations rather than a plant structure with restricted minimum area. That is the structure of the microwave-doppler detecting module  10  is diverse, which facilitates to enhance the applicability of the microwave-doppler detecting module  10 . 
     Specifically, according to this embodiment of the present invention, the wire length of the second radiating source pole  112  corresponding to the first radiating source pole  111  is configured to be a columnar conductive wire, which may be, but not limited to, round columnar conductive wire, square columnar conductive wire, and etc., wherein the wire length parameter L 2  of the second radiating source pole  112  defined between the second feed end  1121  and the end opposite to the second feed end  1121  satisfies that λ/16≤L 2 ≤λ. Correspondingly, wire length parameter L 1  defined on the first radiating source pole  111  between the first feed end  1111  and the end opposite to the first feed end  1111  satisfies that λ/16≤L 1 ≤λ. In this way, the second radiating source pole  112  can be grounded at the second feed end  1121  as an end thereof, so that when the first radiating source pole  111  is fed at the first feed end  1111  as an end thereof, the first radiating source pole  111  and the second radiating source pole  112  can be coupled in an antithetical coupling manner. 
     Preferably, the second radiating source pole  112  and the first radiating source pole  111  are configured to satisfy that the wire lengths thereof from the second feed end  1121  and the first feed end  1111  respectively are close to λ/4 within an error range of λ/128, which means 31λ/128≤L 1 ≤33λ/128 and 31λ/128≤L 2 ≤33λ/28. As a result, the first radiating source pole  111  and the second radiating source pole  112  have wire lengths close to λ/2, which facilitates to enhance the radiation efficiency between the first radiating source pole  111  and the second radiating source pole  112  and correspondingly facilitates to enhance the gain of the microwave-doppler detecting module  10 . 
     Further, according to this embodiment of the present invention, the first radiating source pole  111  and the second radiating source pole  112  are disposed symmetrically to the midpoint of the connection of the first feed end  1111  and the second feed end  1121 . Namely, the first radiating source pole  111  and the second radiating source pole  112  have the same shape and size and the positional relation between the first radiating source pole  111  and the second radiating source pole  112  satisfies that the first radiating source pole  111  is able to surround around the midpoint of the connection of the first feed end  1111  and the second feed end  1121  to turn 180 degrees for at least one direction and to be overlapped with the position of the second radiating source pole  112 . Accordingly, this facilitates to ensure the coupling between the second radiating source pole  112  and the first radiating source pole  111  in an antithetical manner as well as facilitates to maintain the symmetry of the radiation space  100 , which correspondingly maintain the stability of the detection range of the microwave-doppler detecting module  10 . 
     Specifically, according to this embodiment of the present invention, the first radiating source pole  111  and the second radiating source pole  112  being configured to be columnar conductive wires are coaxially arranged. In other words, the first radiating source pole  111  is continually extended from the second feed end  1121  toward the first feed end  1111  and from the first feed end  1111  as an end along the connection of the first feed end  1111  to the second feed end  1121 . The second radiating source pole  112  is continually extended from the first feed end  1111  toward the second feed end  1121  and from the second feed end  1121  as an end toward the connection of the first feed end  1111  to the second feed end  1121 . Accordingly, the structural relation that the first radiating source pole  111  and the second radiating source pole  112  are disposed symmetrically to the midpoint of the connection of the first feed end  1111  and the second feed end  1121 . 
     Further, the microwave-doppler detecting module  10  also comprises a circuit board  13  and a circuit unit  14  loaded on the circuit board  13 , wherein the circuit unit  14  comprises a oscillation circuit module  141  and a frequency mixing wave detection unit  142 , wherein the first radiating source pole  111  and the second radiating source pole  112  are electrically coupled with different poles of the oscillation circuit module  141  respectively at the first feed end  1111  and the second feed end  1121 . Specifically, the first radiating source pole  111  is feedably connected with the feeder pole of the oscillation circuit module  141  at the first feed end  1111 , while the second radiating source pole  112  is electrically connected with the grounding pole of the oscillation circuit module  141  at the second feed end  1121 . In which, the frequency mixing wave detection unit  142  is electrically coupled with the oscillation circuit module  141  and the antithetical dipoles  11 , wherein the oscillation circuit module  141  is allowed to be powered to output a feed signal from the feeder pole thereof and to ground the grounding pole thereof. In other words, the oscillation circuit module  141  is allowed to be powered so as to be an excitation signal feed source, such that when the oscillation circuit module  141  is powered, the first radiating source pole  111  and the second radiating source pole  112  are fed by the same source of the oscillation circuit module  141  at the first feed end  1111  and the second feed end  1121  respectively, so as to emit a sounding wave beam and receive an echo of the sounding wave beam. In which, an echo signal is generated correspondingly to the receiving of the echo. The frequency mixing wave detection unit  142  outputs an intermediate-frequency signal corresponding to the frequency difference between the feed signal and the echo signal. Then, based on the Doppler Effect, the intermediate-frequency signal is corresponding to the movement of the object reflecting the sounding wave beam and producing the echo correspondingly. Hence, the microwave-doppler detecting module is suitable for sensing and detecting object movement. 
     It is worth mentioning that the first radiating source pole  111  and the second radiating source pole  112  respectively utilize the first feed end  1111  and the second feed end  1121  as the ends thereof so that when the first radiating source pole  111  and the second radiating source pole  112  are fed by the same source at the first feed end  1111  and the second feed end  1121  respectively, the electric potentials and the electric currents of the first radiating source pole  111  the second radiating source pole  112  are in an antithetical distribution state, which is corresponding to the antithetical coupling between the second radiating source pole  112  and the first radiating source pole  111 . Namely, the coupling between the second radiating source pole  112  and the first radiating source pole  111  is simplified. Therefore, the corresponding data processing of the microwave-doppler detecting module  10  can be simplified as well, such as that the correlations between the intermediate-frequency signal output by the frequency mixing wave detection unit  142  and the corresponding object movement is increased, so as to simplify the corresponding data processing of the microwave-doppler detecting module  10 . This facilitates to lower the costs of the microwave-doppler detecting module  10  and increase the stability and accuracy of the microwave-doppler detecting module  10 . 
     In particular, according to this embodiment of the present invention, the electromagnetic reflecting surface  12  is obstructed between the circuit unit  14  and the first radiating source pole  111  and the second radiating source pole  112 , so that the electromagnetic radiation produced by the coupling of the first radiating source pole  111  and the second radiating source pole  112  radiated from the first radiating source pole  111  and the second radiating source pole  112  toward the circuit unit  14  can be reflected by the electromagnetic reflecting surface  12  in order to avoid interference to the circuit unit  14 , which facilitates to enhance the anti-interference ability of the microwave-doppler detecting module  10 . 
     Specifically, according to this embodiment of the present invention, the electromagnetic reflecting surface  12  is loaded on the side of the circuit board  13  opposite to the side loading the circuit unit  14 . In other words, the electromagnetic reflecting surface  12  is formed on a corresponding conductive layer (e.g. copper layer and etc.) on the side of the circuit board  13  opposite to the side loading the circuit unit  14 . In which, the first radiating source pole  111  and the second radiating source pole  112  are arranged spacingly to the electromagnetic reflecting surface  12  in the space corresponding to the electromagnetic reflecting surface  12 , so as to utilize the electromagnetic wave reflection characteristic of the electromagnetic reflecting surface  12  and the structural relation that the first radiating source pole  111  and the second radiating source pole  112  are arranged spacingly to the electromagnetic reflecting surface  12  in the space corresponding to the electromagnetic reflecting surface  12  to create a directional radiation characteristic of the microwave-doppler detecting module  10  from the electromagnetic reflecting surface  12  toward the directions of the first radiating source pole  111  and the second radiating source pole  112 . In other words, it correspondingly creates the sensing direction of the microwave-doppler detecting module  10  from the electromagnetic reflecting surface  12  toward the directions of the first radiating source pole  111  and the second radiating source pole  112 , so that the microwave-doppler detecting module  10  is adapted for detecting and sensing the object activity in the directional space corresponding to the sensing direction. Besides, it also facilitates to avoid the microwave-doppler detecting module  10  from self-activating and avoid the electromagnetic radiation produced from the coupling between the first radiating source pole  111  and the second radiating source pole  112  from interfering the circuit unit  14  loaded on the circuit board  13 , so as to enhance the anti-interference ability of the microwave-doppler detecting module. 
     In other words, based on the antithetical coupling mode between the first radiating source pole  111  and the second radiating source pole  112 , the microwave-doppler detecting module  10  has a radiation direction corresponding to the radial direction of the connection of the first feed end  1111  and the second feed end  1121 , so that when the electromagnetic reflecting surface  12  is provided at the radiation direction, the radiation from the first radiating source pole  111  and the second radiating source pole  112  toward the electromagnetic reflecting surface  12  can be reflected to construct the sensing direction of the microwave-doppler detecting module  10  from the electromagnetic reflecting surface  12  toward the first radiating source pole  111  and the second radiating source pole  112  as well as to enhance the electromagnetic radiation of the sensing direction, which facilitates to enhance the directional detection range of the microwave-doppler detecting module  10 . 
     In particular, the electromagnetic reflecting surface  12  is preferably configured to satisfy that the size thereof parallel to the direction of the connection of the first feed end  1111  and the second feed end  1121  is greater than or equal to λ/4 and the size thereof perpendicular to that direction of connection is greater than or equal to λ/4 as well, so as to enhance the reflex action of the electromagnetic reflecting surface  12  for the radiation of the direction from the first radiating source pole  111  and the second radiating source pole  112  toward the electromagnetic reflecting surface  12 . 
     Further, the microwave-doppler detecting module  10  also comprises a first feeder wire  15  and a second feeder wire  16 , wherein the first radiating source pole  111  is electrically coupled with the feeder pole of the oscillation circuit module  141  at the first feed end  1111  through the first feeder wire  15 , wherein the second radiating source pole  112  is electrically connected with the grounding pole of the oscillation circuit module  141  at the second feed end  1121  through the second feeder wire  16 , so as to form and create a circuit connection structure among the first radiating source pole  111  and the second radiating source pole  112  and the circuit unit  14  through the first feeder wire  15  and the second feeder wire  16  and to form and create a structural relation that utilizes the supports of the first feeder wire  15  and the second feeder wire  16  for the first radiating source pole  111  and the second radiating source pole  112  to arrange the first radiating source pole  111  and the second radiating source pole  112  spacingly to the electromagnetic reflecting surface  12  in the space corresponding to the same side of the electromagnetic reflecting surface  12 . 
     Specifically, according to this embodiment of the present invention, the first radiating source pole  111  is integrally extended from the first feed end  1111  on the first feeder wire  15 , wherein the second radiating source pole  112  is integrally extended from the second feed end  1121  on the second feeder wire  16 . This simplifies the structure of the microwave-doppler detecting module  10  and facilitates to maintain the uniformity of the impedance of the microwave-doppler detecting module  10 , so as to benefit the impedance matching of the microwave-doppler detecting module  10 . 
     Further, the first feeder wire  15  and the second feeder wire  16  are parallel to each other. The distance between the first feeder wire  15  and the second feeder wire  16  corresponding to the distance between the first feed end  1111  and the second feed end  1121  satisfies to be smaller than or equal to λ/32 and, preferably, close to the range of λ/128, so that when the first radiating source pole  111  and the second radiating source pole  112  are fed through the first feeder wire  15  and the second feeder wire  16  respectively, the coupling effect between the first feeder wire  15  and the second feeder wire  16  can be reduced, so as to facilitate to reduce the depletion of the first feeder wire  15  and the second feeder wire  16 . In other words, the echo depletion S 11  of the first feeder wire  15  and the second feeder wire  16  is reduced, which facilitates to enhance the gain of the microwave-doppler detecting module  10 . 
     Referring to  FIG. 4 , the radiation direction of the microwave-doppler detecting module  10  corresponding to the radiation space  100  according to the above embodiment of the present invention is illustrated. Based on the figure, the microwave-doppler detecting module  10  has a radiation gain greater than 7 dB in the directional radiation direction, which is the direction perpendicular to the plane of the X-axis and the Y-axis on the figure. Besides, the radiation space  100  protrudes from the direction. Correspondingly, the projection of the radiation space  100  presents a closely complete oval shape, which is different from microwave detection modules of conventional columnar radiation source structure which projection in the directional radiation direction thereof presents a ring shape with a detection dead zone in the middle thereof. The radiation space  100  of the microwave-doppler detecting module  10  protrudes in the directional radiation direction to avoid forming a detection dead zone. 
     In particular, based on the adjustment of the positional relation between the first radiating source pole  111  and the second radiating source pole  112 , the radiation space  100  may be adjusted to correspondingly change the angle and direction of the detection of the microwave-doppler detecting module  10  from the electromagnetic reflecting surface  12  toward the direction of the first radiating source pole  111  and the second radiating source pole  112 , so as to enhance the applicability of the microwave-doppler detecting module  10 . 
     According to one embodiment, the positional relation between the first radiating source pole  111  and the second radiating source pole  112  is capable of being adjusted through adjusting the first radiating source pole  111  and the second radiating source pole  112  to turn around the first feed end  1111  and the second feed end  1121  respectively. According to one embodiment of the present invention, the first radiating source pole  111  and the second radiating source pole  112  are respectively turned around the first feed end  1111  and the second feed end  1121  in the direction close to the electromagnetic reflecting surface  12  for adjustment. That is the first radiating source pole  111  is configured to be a columnar conductive wire extended from the first feed end  1111  as an end toward the connection direction of the second feed end  1121  to the first feed end  1111  and toward the direction of the electromagnetic reflecting surface  12  at the same time, wherein the second radiating source pole  112  is configured to be a columnar conductive wire extended from the second feed end  1121  as an end toward the connection direction of the first feed end  1111  to the second feed end  1121  and toward the direction of the electromagnetic reflecting surface  12 . 
     It is worth mentioning that by adjusting the shape of the second radiating source pole  112  and the first radiating source pole  111 , such as through bending the second radiating source 112  and the first radiating source pole  111  to adjust their shapes, the size of the microwave-doppler detecting module  10  can be further reduced while the wire length parameter L 2  of the second radiating source pole  112  satisfies that λ/16≤L 2 ≤λ and the wire length parameter L 1  of the first radiating source pole  111  satisfies that λ/16≤L 1 ≤λ. In other words, while the antithetical coupling between the second radiating source pole  112  and the first radiating source pole  111  is ensured, it facilitates to reduce the size of the microwave-doppler detecting module  10 . In particular, based on the adjustment of the shape of the first radiating source pole  111  and the second radiating source pole  112  or the adjustment of the positional relation between the first radiating source pole  111  and the second radiating source pole  112 , the radiation space  100  can be adjusted to correspondingly change the coverage area of the electromagnetic wave radiated by the microwave-doppler detecting module  10 , so as to enhance the applicability of the microwave-doppler detecting module  10 . 
     For example, referring to  FIG. 5  of the drawings, the adjustment of the shapes of the first radiating source pole  111  and the second radiating source pole  112  for the microwave-doppler detecting module  10  according to an alternative mode of the above preferred embodiment of the present invention is illustrated. According to this alternative mode of the present invention, the first radiating source pole  111  is extended from the first feed end  1111  to the direction of the second feed end  1121  to the first feed end  1111  and the direction close to the electromagnetic reflecting surface  12 , while the second radiating source pole  112  is extended from the second feed end  1121  to the direction of the first feed end  1111  to the second feed end  1121  and the direction close to the electromagnetic reflecting surface  12 . In other words, the adjustment of the shapes of the first radiating source pole  111  and the second radiating source pole  112  forms the conditions that the end of the first radiating source pole  111  opposite to the first feed end  1111  is, comparing to the first feed end  1111 , closer to the electromagnetic reflecting surface  12  and that the end of the second radiating source pole  112  opposite to the second feed end  1121  is, comparing to the second feed end  1121 , closer to the electromagnetic reflecting surface  12 . 
     Especially, the first radiating source pole  111  is extended from the first feed end  1111  to the direction of the second feed end  1121  to the first feed end  1111  and the direction approaching the electromagnetic reflecting surface  12 . The second radiating source pole  112  is extended from the second feed end  1121  to the direction of the first feed end  1111  to the second feed end  1121  and the direction approaching the electromagnetic reflecting surface  12 . The sizes corresponding to the first radiating source pole  111  and the second radiating source pole  112  in a direction perpendicular to the electromagnetic reflecting surface  12  are both within the range of being greater than or equal to λ/32 and smaller than or equal to λ/4, so as to ensure the antithetical coupling of the first radiating source pole  111  and the second radiating source pole  112  and to reduce the size of the microwave-doppler detecting module  10  based on the size arrangement corresponding to the first radiating source pole  111  and the second radiating source pole  112  in the direction perpendicular to the electromagnetic reflecting surface  12  as well as to allow the radiation space  100  of the microwave-doppler detecting module  10  to be adjusted. 
     Specifically, according to this alternative mode of the present invention, the first radiating source pole  111  and the second radiating source pole  112  are each bent for once. Corresponding to the bent first radiating source pole  111  is extended from the first feed end  1111  along a direction from the second feed end  1121  toward the first feed end  1111  and then extended in another direction towards the electromagnetic reflecting surface  12 , the bent second radiating source pole is extended from the second feed end  1121  along a direction from the first feed end  1111  towards the second feed end  1121  and then extended in another direction towards the electromagnetic reflecting surface  12 . Accordingly, the first and second radiating source poles  111 ,  112  are correspondingly formed in such a manner that one end of the first radiating source pole  111 , opposite to the first feed end  1111 , is closer to the electromagnetic reflecting surface  12  with respect to the first feed end  1111 , and that one end of the second radiating source pole  112 , opposite to the second feed end  1121 , is closer to the electromagnetic reflecting surface  12  with respect to the second feed end  1121 . 
     Hence, according to this alternative mode of the preferred embodiment of the present invention, the size of the portion of the first radiating source pole  111  along a direction perpendicular to the electromagnetic reflecting surface  12  is arranged with respect to the distance L 11  from the end of the first radiating source pole  111  relative to the first feed end  1111  and the bent position of the first radiating source pole  111 , where the L 11  satisfies that λ/32≤L 11 ≤λ/4. The size of the portion of the second radiating source pole  112  along a direction perpendicular to the electromagnetic reflecting surface  12  is arranged with respect to the distance L 21  from the end of the second radiating source pole  112  relative to the second feed end  1121  and the bent position of the second radiating source pole  112 , where the L 21  satisfies that λ/32≤L 21 ≤λ/4. Based on the size arrangements corresponding to the L 11  and the L 21 , the radiation space  100  of the microwave-doppler detecting module  10  can be adjusted and the gain of the corresponding microwave-doppler detecting module  10  can be adjusted as well. 
     Referring to  FIG. 6  of the drawings of the present invention, the radiation direction of the microwave-doppler detecting module  10  corresponding to the radiation space  100  according to the above alternative mode of the preferred embodiment of the present invention is illustrated. According to the figure, the microwave-doppler detecting module  10  also has a radiation gain greater than 7 dB in the directional radiation direction, which is the direction perpendicular to the plane of the X-axis and the Y-axis in the figure. Especially, a difference from the radiation space  100  of the microwave-doppler detecting module of the above preferred embodiment is that, according to this alternative mode of the present invention, based on the adjustment of the shapes of the first radiating source pole  111  and the second radiating source pole  112 , under the conditions that the end of the first radiating source pole  111  opposite to the first feed end  1111  is, with respect to the first feed end  1111 , closer to the electromagnetic reflecting surface  12  and that the end of the second radiating source pole  112  opposite to the second feed end  1121  is, with respect to the second feed end  1121 , closer to the electromagnetic reflecting surface  12 , the radiation space  100  is adjusted into a condition that a cross section thereof perpendicular to the directional radiation direction is close to a full and complete circle, so as to facilitates to enhance the applicability of the detection of the microwave-doppler detecting module  10  for the object activities in the directional space in various application sites. In addition, another difference from the conventional microwave detection module of columnar radiation source structure and microwave detection module of flat radiation source structure which cross section perpendicular to the directional radiation direction thereof is in a ring-shape that has a detection dead zone in the middle thereof is that the radiation space  100  of the microwave-doppler detecting module  10  protrudes at the directional radiation direction, which avoids detection dead zone. 
     It is worth mentioning that, according to the above alternative mode, there are structural relations that the first radiating source pole  111  is extended from the first feed end  1111  toward the direction of the second feed end  1121  to the first feed end  1111  and toward the direction of the electromagnetic reflecting surface  12 , and that the second radiating source pole  112  is extended from the second feed end  1121  toward the direction of the first feed end  1111  to the second feed end  1121  and toward the direction of the electromagnetic reflecting surface  12 . In one alternative mode of the preferred embodiment of the present invention, the first radiating source pole  111  is extended from the first feed end  1111  as an end towards the direction of the second feed end  1121  to the first feed end  1111  and the direction close to the electromagnetic reflecting surface  12  at the same time, and that the second radiating source pole  112  is extended from the second feed end  1121  as an end toward the direction of the first feed end  1111  to the second feed end  1121  and the direction close to the electromagnetic reflecting surface  12  at the same time, so as to form and create a condition that the end of the second radiating source pole  112  opposite to the second feed end  1121 , with respect to the second feed end  1121 , is closer to the electromagnetic reflecting surface  12 , which facilitates to adjust the radiation space  100  into a condition that the cross section thereof perpendicular to the directional radiation direction is close to a full and complete circle, so as to enhance the applicability of the detection of the microwave-doppler detecting module  10  for the object activities in the directional space in various application sites. 
     For example, according to some embodiments of the present invention, the first radiating source pole  111  and the second radiating source pole  112  are arranged in a bending manner. Specifically, the first radiating source pole  111  is a columnar curvy conductive wire formed through extending from the first feed end  1111  as an end along a connection direction from the second feed end  1121  towards the first feed end  1111  and a direction towards the electromagnetic reflecting surface  12  at the same time, wherein the second radiating source pole  112  is a columnar curvy conductive wire formed through extending from the second feed end  1121  as an end along a connection direction from first feed end  1111  towards the second feed end  1121  and a direction towards the electromagnetic reflecting surface  12  at the same time. 
     In other words, the curvy shape of the first radiating source pole  111  is a result that the second feed end  1121  extends toward the connection direction of the first feed end  1111  and the direction towards the electromagnetic reflecting surface  12  in a nonlinear manner. Similarly, the curvy shape of the second radiating source pole  112  is a result that the first feed end  1111  extends toward the connection direction of the second feed end  1121  and the direction towards the electromagnetic reflecting surface  12  in a nonlinear manner. For an example, each of the first radiating source pole  111  and the second radiating source pole  112  is bent towards the direction closer to the electromagnetic reflecting surface  12  to form the columnar curvy conductive wire. For another example, each of the first radiating source pole  111  and the second radiating source pole  112  is bent in the direction deviating from the electromagnetic reflecting surface  12  to form columnar curvy conductive wires. 
     Further, referring to  FIGS. 7 and 8  of the drawings of the present invention, the microwave-doppler detecting module  10  according to another alternative mode of the above preferred embodiment of the present invention is illustrated. Particularly, according to this another alternative mode of the preferred embodiment of the present invention, the first feeder wire  15  has a first feeder section  151  and the second feeder wire  16  has a second feeder section  165 . The first feeder section  151  and the second feeder section  165  are parallel columnar straight conductive wires extended from the first feed end  1111  and the second feed end  1121  respectively, so that a distance between the first feeder section  151  and the second feeder section  165  and a corresponding distance between the first feed end  1111  and the second feed end  1121  satisfies to be smaller than or equal to λ/32 and a range preferably close to λ/128, so that coupling function between the first feeder section  151  and the second feeder section  165  can be reduced, which facilitates to reduce the depletion of the first feeder wire  15  and the second feeder wire  16 . In other words, the echo depletion S 11  of the first feeder wire and the second feeder wire is reduced, which facilitates to further enhance the gain of the microwave-doppler detecting module  10 . 
     In particular, according to this another alternative mode of the preferred embodiment of the present invention, the first feeder wire  15  further has a first coupling section  152  integrally extended from the first feeder section  151 , and the second feeder wire  16  further has a second coupling section  166  integrally extended from the second feeder section  165 . In other words, the first feeder section  151  is electrically coupled with the oscillation circuit module  141  and affixedly coupled with the circuit board  13  through the first coupling section  152 , and that the second feeder section  165  is electrically coupled with the earth potential of the oscillation circuit module  141  and affixedly coupled with the circuit board  13  through the second coupling section  166 . The first coupling section  152  is integrally extended from the first feeder section  151  in a direction deviating from the first feeder section  151 . The second coupling section  166  is integrally extended from the second feeder section  165  in a direction deviating from the second feeder section  165 . Therefore, the lengths of the first feeder wire  15  and the second feeder wire  16  can be configured through the designs of the lengths and shapes of the first coupling section  152  and the second coupling section  166  respectively, so as to facilitate to not only satisfy the impedance matching and corresponding resonance frequency design of the microwave-doppler detecting module  10  based on the arrangement of the corresponding lengths of the first feeder wire  15  and the second feeder wire  16 , but also maintain the distance between the electromagnetic reflecting surface  12  and a midpoint of the connection of the first feed end  1111  and the second feed end  1121  in a proper range, such as being greater than or equal to λ/32 and smaller than or equal to λ/2 or close to the preferable range of λ/4, based on the shape design of the first coupling section  152  and the second coupling section  166 . That is, based on the design of the lengths and shapes of the first coupling section  152  and the second coupling section  166 , the microwave-doppler detecting module  10  is able to not only satisfy the corresponding impedance matching and resonance frequency design, but also enhance the reflex action of the electromagnetic reflecting surface  12  for the radiation in the direction from the first radiating source pole  111  and the second radiating source pole  112  to the electromagnetic reflecting surface  12 , so as to facilitate to extent the detecting distance of the microwave-doppler detecting module  10 . 
     In other words, based on the designs of the shapes and the lengths of the first coupling section  152  and the second coupling section  166 , the distance between the electromagnetic reflecting surface  12  and the midpoint of the connection of the first feed end  1111  and the second feed end  1121  can be maintained or shortened within the range greater than or equal to λ/32 and smaller than or equal to λ/2. Besides, the microwave-doppler detecting module  10  can satisfy the corresponding impedance matching and the resonance frequency design. Hence, the microwave-doppler detecting module  10  is able to not only satisfy the corresponding impedance matching and the resonance frequency design, but also have higher gain. 
     Further, according to this another alternative mode of the preferred embodiment of the present invention, the first coupling section  152  and the second coupling section  166  integrally extended away from the first feeder section  151  and the second feeder section  165  respectively, so that the distance between the first coupling section  152  and the second coupling section  166  in the directions perpendicular to the first feeder section  151  and the second feeder section  165  is larger than the distance between the first feeder section  151  and the second feeder section  165 , so that the first feeder section  151  and the second feeder section  165  which are parallel to each other are in a condition of closing to each other within a distance smaller than or equal to λ/32, which facilitates to electrically couple the first feeder wire  15  with oscillation circuit module  141  at the first coupling section  152  through welding and soldering and to affixedly couple the first feeder wire  15  with the circuit board  13  as well as to electrically couple the second feeder wire  16  with the earth potential of the oscillation circuit module  141  at the second coupling section  166  through welding and soldering and affixedly couple the second feeder wire  16  with the circuit board  13 . 
     Specifically, according to this another alternative mode of the preferred embodiment of the present invention, the distance of the first coupling section  152  and the second coupling section  166  in the direction perpendicular to the first feeder section  151  and the second feeder section  165  is smaller than or equal to λ/8. The distance of the first coupling section  152  and the second coupling section  166  in the direction parallel to the first feeder section  151  and the second feeder section  165  is also smaller than or equal to λ/8. Therefore, it not only ensures the low loss characteristic between the first feeder section  151  and the second feeder section  165  so as to be capable of satisfying the corresponding impedance matching and resonance frequency design based on the design of the lengths and shapes of the first coupling section  152  and the second coupling section  166 , but also reinforces the reflex action of the electromagnetic reflecting surface  12  for the radiations of the directions from the first radiating source pole  111  and the second radiating source pole  112  toward the electromagnetic reflecting surface  12 . 
     It is worth mentioning that, according to this another alternative mode of the preferred embodiment of the present invention, the first coupling section  152  is extended from the end of the first feeder section  151  that is opposite to the first feed end  1111  toward a direction perpendicular to the first feeder section  151  and then toward another direction parallel to the first feeder section  151 , while the second coupling section  166  is extended from the end of the second feeder section  165  that is opposite to the second feed end  1121  toward a direction perpendicular to the second feeder section  165  and then toward another direction parallel to the second feeder section  165 . In some embodiments of the present invention, the first coupling section  152  may be configured to be extended from the end of the first feeder section  151  that is opposite to the first feed end  1111  toward a direction perpendicular to the first feeder section  151  and a direction parallel to the first feeder section  151  at the same time. For example, the first coupling section  152  can be a columnar curvy conductive wire extended from the end of the first feeder section  151  that is opposite to the first feed end  1111  to the direction perpendicular to the first feeder section  151  and the direction parallel to the first feeder section  151  at the same time. Similarly, the second coupling section  166  may be configured to be extended from the end of the second feeder section  165  that is opposite to the second feed end  1121  to the direction perpendicular to the second feeder section  165  and the direction parallel to the second feeder section  165  at the same time. For example, the second coupling section  166  can be a columnar curvy conductive wire extended from the end of the second feeder section  165  that is opposite to the second feed end  1121  to the direction perpendicular to the second feeder section  165  and the direction parallel to the second feeder section  165  at the same time. The present invention shall not be limited here. 
     Further, according to this another alternative mode of the preferred embodiment of the present invention, the high gain microwave-doppler detecting module  10  further comprises a fixing base  17 . The fixing base  17  is attached on a side of the circuit board  13  having the electromagnetic reflecting surface  12  provided thereon. The first feeder wire  15  and the second feeder wire  16  are partially clamped and affixed to the fixing base  17 , so as to facilitates to maintain the first feeder section  151  and the second feeder section  165  in a parallel manner and a condition close to each other within a distance smaller than or equal to λ/32, that facilitates to maintain the uniformity in producing and the stability in utilizing of the high gain microwave-doppler detecting module  10 . 
     Further, referring to  FIG. 9  of the drawings of the present invention, the microwave-doppler detecting module  10  according to another alternative mode of the above preferred embodiment of the present invention. In particular, according to this alternative mode of the preferred embodiment of the present invention, the second feeder wire  16  encircles and surrounds the first feeder wire  15  so as to form and create an electromagnetic shielding cavity  161 , such that when the second feeder wire  16  is grounded, the influence of the coupling between the second feeder wire  16  and the first feeder wire  15  to the coupling between the first radiating source pole  111  and the second radiating source pole  112  can be reduced and the interference of external electromagnetic radiation to the first feeder wire  15  can be shielded, that thereby facilitates to enhance the anti-interference ability of the microwave-doppler detecting module  10 . 
     Preferably, the second feeder wire  16  is arranged being surrounded and encircled by the first feeder wire  15  coaxially, so that when the first radiating source pole  111  is fed at the first feed end  1111  through the first feeder wire  15  and the second radiating source pole  112  is fed at the second feed end  1121  through the second feeder wire  16 , the coupling between the first radiating source pole  111  and the second radiating source pole  112  in an antithetical manner is facilitated. 
     Especially, on the basis of the condition that the second radiating source pole  112  is grounded according to the above embodiment, according to some embodiments, the first radiating source pole  111  is further grounded, so as to reduce the impedance of the microwave-doppler detecting module, so that the quality factor (Q value) of the microwave-doppler detecting module can be increased, which facilitates the anti-interference ability of the microwave-doppler detecting module. 
     Referring to  FIG. 10 , the 3D structure of the microwave-doppler detecting module  10  according to another alternative mode of the above embodiment of the present invention is illustrated. Particularly, comparing to the above preferred embodiment and its alterative modes, according to this alternative mode of the present invention, the first radiating source pole  111  is further electrically connected with the second feeder wire  16  so as to be grounded. 
     Specifically, according to this alternative mode of the present invention, the second feeder wire  16  is arranged to surround around the first feeder wire  15  coaxially and further has a pair of notch positions  162 . The second feeder wire  16  has a pair of notches formed at the notch positions  162  and extended from the end connected with the second radiating source pole  112  along a direction of the first feeder wire  15 . The pair of the notch positions  162  defines a first arm  163  and a second arm  164  of the second feeder wire  16 . That is, the first arm  163  and the second arm  164  are two portions of the second feeder wire  16  wherein the pair of the notch positions  162  is defined therebetween. The second radiating source pole  112  is conductively extended from the second feed end  1121  to the second arm  164  of the second feeder wire  16 . The first radiating source pole  111  is conductively extended from the first feed end  1111  to the first arm  163  of the second feeder wire  16  and is conductively connected with the first feeder wire  15  at the first feed end  1111 , so as to create a condition that the first radiating source pole  111  is grounded. 
     It is worth mentioning that, a notch depth of each of the notches of the second feeder wire  16  from the end of the second feeder wire  16  connected with the second radiating source pole  112  along the direction of the first feeder wire  111  is greater than or equal to λ/128, so that when the first radiating source pole  111  is grounded through the first arm  163  of the second feeder wire  16 , the first radiating source pole  111  can be fed and excited at the first feed end  1111  through the first feeder wire  15 , and the second radiating source pole  112  can be fed at the second feed end  1121  through the second feeder wire  16  at the same time, so as to facilitate coupling between the first radiating source pole  111  and the second radiating source pole  112  in an antithetical manner. 
     It is understandable that, based on the arrangement of the depth of the notches  162 , corresponding impedance can be created, so as to facilitate the impedance matching between the antithetical dipoles  11  and the first feeder wire  15  and the second feeder wire  16  and the oscillation circuit module  141 . 
     Especially, according to this alternative mode of the present invention, the first radiating source pole  111  and the second radiating source pole  112  are bent for once, so as to maintain that the wire length parameter L 2  of the second radiating source pole  112  satisfies λ/16≤L 2 ≤λ and that the wire length parameter L 1  of the first radiating source pole  111  satisfies λ/16≤L 1 ≤λ at the same time, so that the sizes of the second radiating source pole  112  and the first radiating source pole  111  parallel to the direction of the connection of the first feed end  1111  and the second feed end  1121  can be reduced. 
     Further, referring to  FIG. 11  of the drawings of the present invention, based on the concept that the second feeder wire  16  is configured as a dismountable tubular structure, an alternative structure for the microwave-doppler detecting module corresponding to that as illustrated in the  FIG. 10  is illustrated. A difference to the microwave-doppler detecting module  10  as illustrated in  FIG. 10  is that, according to this alternative structure of the present invention, the second feeder wire  16  is configured as a dismountable square tubular structure, which means that the second feeder wire  16  is a square tubular structure that can be assembled in a buckling manner or other dismountable manner. 
     Further referring to  FIG. 12  of the drawings of the present invention, based on the concept that the second feeder wire  16  is configured as a dismountable tubular structure,  FIG. 12  illustrates another alternative structure for the microwave-doppler detecting module corresponding to that in the  FIG. 11 . According to this alternative structure, the end of the first radiating source pole  111  that is opposite to the first feed end  1111  is further extended toward two opposite directions perpendicular to the connection of the first feed end  1111  and the second feed end  1121 , and that the end of the second radiating source pole  112  that is opposite to the second feed end  1121  is further extended toward the two opposite directions perpendicular to the connection of the first feed end  1111  and the second feed end  1121 , so as to suppress the energy accumulation at the end of the first radiating source pole  111  opposite to the first feed end  1111  and to suppress the energy accumulation at the end of the second radiating source pole  112  opposite to the second feed end  1121  when the first radiating source pole  111  and the second radiating source pole  112  are antithetically coupled, so as to facilitate to maintain the stability of the microwave-doppler detecting module  10 . 
     In order to further disclose the present invention, referring to  FIG. 13  of the drawings of the present invention, the 3D structure of another microwave-doppler detecting module  10 A according to another preferred embodiment of the present invention is illustrated. Similarly, the microwave-doppler detecting module  10 A comprises a second radiating source pole  112 A and a first radiating source pole  111 A, wherein the second radiating source pole  112 A has a second feed end  1121 A, while the first radiating source pole  111 A has a first feed end  1111 A, wherein the second feed end  1121 A and the first feed end  1111 A are close to each other within a distance of λ/4, wherein the second radiating source pole  112 A is extended from the second feed end  1121 A as one end, wherein the first radiating source pole  111 A is extended from the first feed end  1111 A as one end, wherein the first radiating source pole  111 A is configured to be adapted for being fed at the first feed end  1111 A, wherein the second radiating source pole is configured to be adapted for being fed at the second feed end  1121 A, so that when the first radiating source pole  111 A is fed at the first feed end  1111 A and the second radiating source pole  112 A is fed by the same source at the second feed end  1121 A, the first radiating source pole  111 A from the first feed end  1111 A along the first radiating source pole  111 A is correspondingly coupled to the corresponding positions of the second radiating source pole  112 A from the second feed end  1121 A along the second radiating source pole  112 A, so as to form the antithetical coupling arrangement between the first radiating source pole  111 A and the second radiating source pole  112 A. 
     A difference from the above preferred embodiment is that, according to this another preferred embodiment of the present invention, the microwave-doppler detecting module  10 A further comprises a medium substrate  18 A, wherein the first radiating source pole  111 A and the second radiating source pole  112 A is provided on the same side of the medium substrate  18 A in a form of microstrip line, so that the shapes and sizes of the first radiating source pole  111 A and the second radiating source pole  112 A can correspondingly be implemented easily based on the technology of microstrip line. 
     The microwave-doppler detecting module  10 A also comprises a circuit board  13 A and a circuit unit  14 A provided on the circuit board  13 A, wherein the circuit unit  14 A comprises an oscillation circuit module  141 A and a frequency mixing wave detection unit  142 A, wherein the first radiating source pole  111 A and the second radiating source pole  112 A are electrically coupled with different poles of the oscillation circuit module  141 A respectively at the first feed end  1111 A and the second feed end  1121 A. Specifically, the first radiating source pole  111 A is feedably connected with the feeder pole of the oscillation circuit module  141 A at the first feed end  1111 A, while the second radiating source pole  112 A is electrically connected with the grounding pole of the oscillation circuit module  141 A at the second feed end  1121 A.

In other words, the oscillation circuit module  141 A is allowed to be powered so as to be an excitation signal feed source, such that when the oscillation circuit module  141 A is powered, the first radiating source pole  111 A and the second radiating source pole  112 A are fed by the same source of the oscillation circuit module  141 A at the first feed end  1111 A and the second feed end  1121 A respectively, so as to emit a sounding wave beam and receive an echo of the sounding wave beam. In which, an echo signal is generated correspondingly to the receiving of the echo. The frequency mixing wave detection unit  142 A outputs an intermediate-frequency signal corresponding to the frequency difference between the feed signal and the echo signal. Then, based on the Doppler Effect, the intermediate-frequency signal is corresponding to the movement of the object reflecting the sounding wave beam and producing the echo correspondingly. Hence, the microwave-doppler detecting module is suitable for sensing and detecting object movement. 
     Further, the first radiating source pole  111 A and the second radiating source pole  112 A are disposed symmetrically to a midpoint of the connection of the first feed end  1111 A and the second feed end  1121 A.

     Especially, according to this another preferred embodiment of the present invention, the second feeder wire  16 A and the first feeder wire  15 A are embodied as that the second feeder wire  16 A is a shielding wire surrounding and encircling the first feeder wire  15 A, wherein the shielding wire is insertably arranged so as to construct the insertable and connectable circuit connection structure among the first radiating source pole  111 A and the second radiating source pole  112 A and the circuit unit  14 A, which facilitates the assembling of the microwave-doppler detecting module  10 A. 
     Similarly, the microwave-doppler detecting module  10 A further has an electromagnetic reflecting surface  12 A provided on the circuit board  13 A, wherein the electromagnetic reflecting surface  12 A is provided on a side of the circuit board  13 A opposite to the other side having the circuit unit  14 A thereon, wherein the radiating source pole  111 A and the second radiating source pole  112 A are arranged spacingly to the electromagnetism reflecting  12 A in a space corresponding to the electromagnetic reflecting surface  12 A, so as to utilize the electromagnetic wave reflection characteristic of the electromagnetic reflecting surface  12 A and the structural relation that the first radiating source pole  111 A and the second radiating source pole  112 A are arranged spacingly to the electromagnetic reflecting surface  12 A in a space corresponding to the electromagnetic reflecting surface  12 A to create a directional radiation characteristic of the microwave-doppler detecting module  10 A from the electromagnetic reflecting surface  12 A toward the directions of the first radiating source pole  111 A and the second radiating source pole  112 A. In other words, with respect to a sensing direction of the microwave-doppler detecting module  10 A defined from the electromagnetic reflecting surface  12 A toward the directions of the first radiating source pole  111 A and the second radiating source pole  112 A, the microwave-doppler detecting module  10 A is adapted for detecting and sensing the object activity in the directional space corresponding to the sensing direction.

     Especially, based on the adjustment of the positional relation between the medium substrate  18 A and the circuit board  13 A, the microwave-doppler detecting module  10 A may have various structural designs, which facilitates to enhance the applicability of the microwave-doppler detecting module  10 A. 
     Specifically, referring to  FIG. 14  of the drawings of the present invention, based on the adjustment of the positional relation between the medium substrate  18 A and the circuit board  13 A, the microwave-doppler detecting module  10 A according to an alternative mode of the above another preferred embodiment of the present invention is illustrated. 
     Specifically, according to this alternative mode of the above another preferred embodiment of the present invention, the medium substrate  18 A is perpendicular to the circuit board  13 A, wherein the connection of the first feed end  1111 A and the second feed end  1121 A is parallel to the circuit board  13 A. In other words, based on the positional relation of the medium substrate  18 A parallel to the circuit board  13 A, according to this alternative mode, the medium substrate  18 A is turned for 90 degrees around the connection of the first feed end  1111 A and the second feed end  1121 A, which correspondingly creates a positional relation that the medium substrate  18 A is perpendicular to the circuit board  13 A and that the connection of the first feed end  1111 A and the second feed end  1121 A is parallel to the circuit board  13 A. 
     It is worth mentioning that, based on the adjustment of the shape of the second radiating source pole  112 A and the first radiating source pole  111 A, if the second radiating source pole  112 A and the first radiating source pole  111 A are extended in a manner to the other side of the medium substrate  18 A, while the second radiating source pole  112 A and the first radiating source pole  111 A both satisfy the requirement that the wire lengths from the second feed end  1121 A and the first feed end  1111 A are respectively greater than or equal to λ/16, the size of the medium substrate  18 A can be reduced so as to the size of the microwave-doppler detecting module  10 A. 
     For instance, according to some embodiments of the present invention, based on the structural relation that the second radiating source pole  112 A and the first radiating source pole  111 A are symmetrical corresponding to the midpoint of the connection between the first feed end  1111 A and the second feed end  1121 A and through the adjustment of the shapes of the second radiating source pole  112 A and the first radiating source pole  111 A, the first radiating source pole  111 A and the second radiating source pole  112 A can be arranged on the same side of the medium substrate  18 A to respectively be extended from the first feed end  1111 A and the second feed end  1121 A to another side of the medium substrate  18 A. In other words, the first feed end  1111 A of the first radiating source pole  111 A and the second feed end  1121 A of the second radiating source pole  112 A are provided on the same side of the medium substrate  18 A, wherein the first radiating source pole  111 A is extended from the first feed end  1111 A as one end along a connection direction from the second feed end  1121 A toward the first feed end  1111 A, and is continuously extended to surround around the edge of the medium substrate  18 A to another side of the medium substrate  18 A, wherein the second radiating source pole  112 A is extended from the second feed end  1121 A as one end along a connection direction from the first feed end  1111 A toward the second feed end  1121 A, and is continually extended to surround around the edge of the medium substrate  18 A to another side of the medium substrate  18 A. 
     According to some embodiments of the present invention, the first radiating source pole  111 A and the second radiating source pole  112 A on different sides of the medium substrate  18 A are respectively extended from the first feed end  1111 A and the second feed end  1121 A to the other sides of the medium substrate  18 A. Specifically, the first feed end  1111 A of the first radiating source pole  111 A and the second feed end  1121 A of the second radiating source pole  112 A are provided on different sides of the medium substrate  18 A, wherein the first radiating source pole  111 A from the side of the medium substrate  18 A with the first feed end  1111 A provided thereon has the first feed end  1111 A as an end to be continually extended to surround around the edge of the medium substrate  18 A to the side of the medium substrate  18 A that provides the second feed end  1121 A. In which, the second radiating source pole  112 A on the side of the medium substrate  18 A having the second feed end  1121 A loaded thereon utilizes the second feed end  1121 A as an end to be continually extended to surround around the edge of the medium substrate  18 A to the side of the medium substrate  18 A that has the first feed end  1111 A. 
     It is understandable that, according to some embodiments of the present invention, both sides of the medium substrate  18 B are allowed to have at least a pair of the antithetical dipoles  11 B be respectively arranged thereon, which can also ensures that the first radiating source pole  111 B and the second radiating source pole  112 B of each pair of the antithetical dipoles  11 B can be antithetically coupled and reinforces the antithetical coupling of the first radiating source pole  111 B of the antithetical dipoles  11 B provided on one side of the medium substrate  18 B and the second radiating source pole  112  of the antithetical dipoles  11 B provided on the other side of the medium substrate  18 B, wherein the present invention shall not be limited here. 
     It is worth mentioning that it is understandable that, based on the disclosure of the microwave-doppler detecting module of the above embodiments and their alternative modes: the second radiating source pole corresponding to the first radiating source pole of a pair of the antithetical dipoles may have various and diverse shapes and sizes, rather than be limited in a plant structure of restricted area. In other words, the grounded second radiating source pole is free from the limitation of having a restricted minimum area for reference ground. Instead, the microwave-doppler detecting module is also capable of being utilized in the application scenarios of the above mentioned microwave detection module of columnar radiation source structure through extending the second radiating source pole and the first radiating source pole out of a corresponding metal plate. Further, contrasting to the microwave detection module of columnar radiation source structure, this microwave-doppler detecting module has a better stability in the corresponding application scenarios because the corresponding metal plate will not affect the coupling between the first radiating source pole and the second radiating source pole thereof. 
     For demonstration, referring to  FIGS. 15 and 16  of the drawings of the present invention, based on the application of the microwave-doppler detecting module in the scenario of the above mentioned microwave detection module of columnar radiation source structure, the present invention further provides a microwave-doppler detecting device.

In which, with respect to the design of the shape of the first radiating source pole and the second radiating source pole  112 , the projected area of the first radiating source pole  111  and the second radiating source pole  112  in the direction perpendicular to the electromagnetic shielding layer  20  on the electromagnetic shielding layer  20  can be reduced, which facilitates to reduce the size of the through hole  22 , which helps to maintain the completeness of the electromagnetic shielding layer  20  and to enhance the stealth of the mounting of the microwave-doppler detecting module  10  in the microwave-doppler detecting device. 
     It is understandable that the first radiating source pole  111  and the second radiating source pole  112  are coupled in an antithetical manner, so that when the first radiating source pole  111  and the second radiating source pole  112  are in the space corresponding to the same side of the electromagnetic shielding layer  20 , the coupling between the first radiating source pole  111  and the second radiating source pole  112  is capable of avoiding the impediment of the electromagnetic shielding layer  20 , so as to facilitate to maintain the detecting stability of the microwave-doppler detecting module  10  mounted in the microwave-doppler detecting device. 
     Especially, according to one embodiment of the present invention, the electromagnetic shielding layer  20  is configured to be a LED light board and have a plurality of LED lights  21  arranged on the side of the second radiating source pole  112  corresponding to the first radiating source pole  111 , wherein based on the shapes of the first radiating source pole  111  and the second radiating source pole  112 , the projected area of the first radiating source pole  111  and the second radiating source pole  112  on the electromagnetic shielding layer in the direction perpendicular to the electromagnetic shielding layer  20  can be reduced, so that the size of the through hole  22  can correspondingly be reduced and the microwave-doppler detecting module  10  is allowed to be mounted on the microwave-doppler detecting device through having first radiating source pole  111  and the second radiating source pole  112  pass through, which facilitates the integrity and completeness of the LED light board and facilitates to avoid the LED light board from rendering dark zone. 
     Corresponding to  FIG. 16 , the microwave-doppler detecting module  10 A as illustrated in  FIG. 13  is embodied in the previously mentioned application scenario of the microwave detection module of columnar radiation source structure, wherein the microwave-doppler detecting device comprises the microwave-doppler detecting module  10 A and an electromagnetic shielding layer  20 A, wherein the electromagnetic shielding layer  20 A has a through hole, wherein the circuit board  13 A is disposed in a shielded space corresponding to a side of the electromagnetic shielding layer  20 A, wherein the first radiating source pole  111 A and the second radiating source pole  112 A are disposed in another space corresponding to another side of the electromagnetic shielding layer  20 A, wherein the first feeder wire  15 A and the second feeder wire  16 A pass through the electromagnetic shielding layer  20 A through the through hole  22 A to form and construct the circuit connection structure among the first radiating source pole  111 A and the second radiating source pole  112 A and the circuit unit  14 A, so as to utilize the arrangement of the first radiating source pole  111 A and the second radiating source pole  112 A in a space outside of the shielded space to perform the activity sensing and detecting for the space outside of the shielded space. In which, with respect to the design of the shape of the first radiating source pole and the second radiating source pole  112 A, the projected area of the first radiating source pole  111 A and the second radiating source pole  112 A in the direction perpendicular to the electromagnetic shielding layer  20 A on the electromagnetic shielding layer  20 A can be reduced, which facilitates to reduce the size of the through hole  22 A, which helps to maintain the completeness of the electromagnetic shielding layer  20 A and to enhance the stealth of the mounting of the microwave-doppler detecting module  10 A in the microwave-doppler detecting device. 
     It is worth mentioning that when the second feeder wire  16 A and the first feeder wire  15 A are configured in a manner that the second feeder wire  16 A is a shielding wire surrounding and encircling the first feeder wire  15 A and that the shielding wire is insertably arranged in a manner to form a insertable and connectable circuit connection structure among the first radiating source pole  111 A and the second radiating source pole  112 A and the circuit unit  14 A, such as that the shielding wire is configured to be a insertable and connectable structure with the medium substrate  18 A or the circuit board  13 A so as to form an insertable and connectable circuit connection structure among the first radiating source pole  111 A and the second radiating source pole  112 A and the circuit unit  14 A, the size of the through hole  22 A of the electromagnetic shielding layer  20  is allowed to be configured to meet the wire diameter of the shielding wire, which facilitates to reduce the size of the through hole  22 A, so as to facilitate to maintain the integrity and completeness of the electromagnetic shielding layer  20 A and enhance the stealth of the microwave-doppler detecting module  10 A mounted on the microwave-doppler detecting device.

     It is understandable that based on the electromagnetic wave reflection characteristic of the electromagnetic shielding layer  20 A, the electromagnetic reflecting surface  12 A can be equivalently formed on the electromagnetic shielding layer  20 A. In other words, the electromagnetic reflecting surface  12 A corresponding formed on the circuit board  13 A may be omitted. In other words, according to one embodiment of the present invention, the electromagnetic reflecting surface  12 A corresponding formed on the circuit board  13 A shall not be a limitation to the microwave-doppler detecting device of the present invention. 
     It is worth mentioning that the above embodiments and alternative modes thereof are only examples, based on an antithetical coupling manner, the microwave-doppler detecting module comprises at least a pair of the antithetical dipoles, wherein the shapes and sizes of the first radiating source pole and the second radiating source pole of each pair of the antithetical dipoles may vary and the first radiating source pole and the second radiating source pole in the shielded space corresponding to a side of the electromagnetic shielding layer may extend through the through hole to a space out of the shielded space corresponding to the other side of the electromagnetic shielding layer, so as for achieving the installation of the microwave-doppler detecting module on the corresponding microwave-doppler detecting device, for achieving the activity detecting outside of the shielded space through breaking through the shielded space, and for maintaining the integrity and completeness of the electromagnetic shielding layer. It not only benefits the stealth of the installation of the microwave-doppler detecting module on the microwave-doppler detecting device, but also achieves detection to the space outside of the shielded space without blind angle.
