     BACKGROUND OF THE INVENTION  
     1. Field of the Invention 
     The present, invention relates to an electronic device having a transmission line pattern embedded in a case thereof and a method for manufacturing the same. 
     2. Description of the Related Art 
     With the rapid development of semiconductor integrated circuit technology and information technology, various portable electronic devices such as a portable multimedia player (PMP), a personal digital assistant (PDA), a smart phone, a laptop, and the like have become necessities of modern life. 
     Further, as portable electronic devices have come to be widely used, user requirements have been diversified, and as a result, portable electronic devices having multiple functions and which can be conveniently used have been continuously developed. For example, diversified functions such as digital broadcast transmitting and receiving (e.g., digital multimedia broadcasting (DMB)), navigation, Wibro, WIFI, Bluetooth, and the like nave been incorporated into portable electronic devices. 
     In recent years, with the miniaturizing and thinning tendencies in the field of portable electronic devices, circuits having diversified functions need to be integrated into a limited internal space of portable electronic devices. In this case, in order to maximally utilize the internal space of portable electronic devices, spatially separated components, e.g., a printed circuit board (PCB), an antenna, an interface card, and the like are used. 
     However, in this case, a connection medium such as a flexible printed circuit board (FPCB) or a coaxial cable should be used in order to transfer a signal, such as a digital signal or a high-frequency signal transmitted through the antenna, between the PCBs, and a space for the connection media should be allocated within the inner part of the portable electronic device. Therefore, it is inefficient in terms of spatial utilization.

For example, the first to fourth connection members  310  to  340  may be formed by a C-clip or a Pogo-pin. 
     The first to fourth connection members  310  to  340  may each be integrated with a corresponding one of the first PCB  130  and the second PCB  150  or formed as an additional member to be attached to a corresponding one of the terminals of the predetermined circuits of the first PCB  130  and the second PCB  150 . 
     In  FIG. 3 , the first and second connection members  310  and  320  are formed as additional members and have ends respectively connected to the terminals of the predetermined circuits of the first PCB  130  and the second PCB  150  and other ends respectively, elastically connecting with the first and second terminal portions  211  and  212 , but the present invention is not limited thereto.

Here, the first connection portion  225  may be formed between one end of the second circuit pattern  224  and the third terminal portion  221 , and the second connection portion  226  may be formed between the other end of the second circuit pattern  224  and the fourth terminal portion  222 , so as to connect them to each other. 
     Although the circuit pattern bodies  210  and  220  transmit signals between circuits having predetermined functions of the first PCB  130  and the second PCB  150  in the exemplary embodiment, the present invention is not limited thereto and the line pattern bodies  210  and  220  may transmit high-frequency signals between a PCB having a matching circuit and an antenna and transmit signals between the antenna and an interface card.

Further, the central conductor pattern  433 , and the first ground conductor  431   a  and the second ground conductor  431   b  may be parallel to each other. 
     As shown in  FIG. 5D , the line pattern according to an exemplary embodiment of the present invention may a coplanar waveguide with ground (CPWG). The CPWG further includes a ground metal plate on the bottom of the CPW shown in  FIG. 5C .

     Hereinafter, a method for manufacturing a mobile communication terminal which is an electronic device according to an exemplary embodiment of the present invention will be described. 
     First, when a predetermined manufacturing method of the present invention is schematically described, a line pattern body having a line pattern and a terminal portion is manufactured, the line pattern body is insert-injection-molded such that the terminal portion is exposed while the line pattern is embedded in a case, and the terminal portion and parts of a main body are electrically connected with each other so as to complete the electronic device according to an exemplary embodiment the present invention. 
       FIGS. 6A and 6B  are schematic cross-sectional views showing a state in which a resin material is filled in a line pattern body frame and a manufacturing mold therefor according to an exemplary embodiment of the present invention. 
     Referring to  FIGS. 6A and 6B , a line pattern  214  that transmits signals between components of a main body is formed by applying a conductive material to one surface of an FPCB, and first and second terminal portions  211  and  212  are formed at both ends of the line pattern  214  to thereby manufacture a line pattern body  210 . 
     In this case, the application of the conductive material to one surface of a PCB may be performed by a method of sputtering, printing, plating, stamping, drawing, or dispensing a pattern corresponding to the line pattern  214 . 
     Further, the first terminal portion  211  and the second terminal portion  212  may be formed in locations corresponding to terminals of components of the main body to be electrically connected to each other, e.g., PCBs, a PCB and an antenna, and an antenna and an interface card. 
     The line pattern body  210  is disposed in a manufacturing mold  500  for a line pattern body frame, and a resin material may then be filled in an inner space  530  of the manufacturing mold  500  for the line pattern body frame. 
     The manufacturing mold  500  for the line pattern body frame includes an upper mold  510  contacting one surface of the FPCB of the line pattern body  210  opposing the other surface thereof on which the line pattern  214  is formed, and a lower mold  520  filled with the resin material. 
     When the line pattern body  210  is disposed in the upper mold  510  and the lower mold  520  which are combined with each other, the resin material is filled in the inner space  530  formed by the combination of the upper mold  510  and the lower mold  520  through an inlet  540 . 
     In this case, portions of the bottom of the lower mold  520  corresponding to the first terminal portion  211  and the second terminal portion  212  are projected, and groove portions  522  filled with the resin material are formed in portions thereof other than the portions corresponding to the first terminal portion  211  and the second terminal portion  212 . 
     Therefore, when the resin material is filled in the inner space  530 , the resin material is filled in the part other than the portions where the first terminal portion  211  and the second terminal portion  212  are formed, such that when the line pattern body frame  230  is separated from the manufacturing mold  500  of the line pattern body  230 , the first terminal portion  211  and the second terminal portion  212  may be exposed on the bottom of the line pattern body frame  230 . 
     Herein, the line pattern body frame  230  may serve as a primary injection product for embedding the line pattern  214  in the case. 
       FIGS. 7A and 7B  are schematic cross-sectional views showing a state in which a resin material is filled in a case frame having a line pattern embedded therein and a manufacturing mold therefor according to an exemplary embodiment of the present invention. 
     Referring to  FIGS. 7A and 7B , a line pattern body frame  230  is disposed in a manufacturing mold  600  for a case frame, and a resin material is filled in the manufacturing mold  600  for the case frame to thereby manufacture a case frame (alternatively, a case  120 ) in which the line pattern  214  is embedded. 
     The manufacturing mold  600  for the case frame includes an upper mold  610  with an inner space  630  filled with the resin material and a lower mold  620  with an inner space where the line pattern body frame  230  is disposed to form the case frame  120 . 
     The upper mold  610  has a groove  612  to form the inner space  630  between itself and one surface of the line pattern body frame  230  disposed therein. The bottom of the lower mold  620  may have the same shape as the surface on which the first terminal portion  211  and the second terminal portion  212  are formed. 
     As a result, the resin material is prevented from being applied to the surface of the line pattern body frame  230  on which the first terminal portion  211  and the second terminal portion  212  are formed. Therefore, the first terminal portion  211  and the second terminal portion  212  may be exposed on the bottom of the case frame  120 . 
     The line pattern body frame  230  is disposed in the lower mold  620 , and the lower mold  620  and the upper mold  610  are then combined together. Thereafter, the resin material is injected into the inner space  630 , formed by the joined lower and upper molds  620  and  610 , through the inlet  640 , such that the resin material is filled to cover an opposite surface to the surface on which the terminal portions  211  and  212  of the line pattern body frame  230  are exposed. The part filled with the resin material constitutes the case frame  120 . 
     Herein, the case frame  120  may serve as a secondary injection product for embedding the line pattern  214  in the case. 
     Although the line pattern body frame  230  and the case frame  120  are formed by insert-injection molding, it is merely exemplary and the present invention is nor limited thereto. For example, the line pattern body frame  230  may be manufactured by attaching the line pattern body  210  to a frame having a predetermined shape, and the case frame  120  may be manufactured by attaching the manufactured line pattern body frame  230  to a frame having the shape of a previously manufactured case. 
     When the case  120  in which the line pattern  214  is embedded is completed, the circuits of the PCBs  130  and  150  of the main body are electrically connected with each other by using connection members  310  and  320 . 
     This does not require an additional assembly process and may be made by assembling the case  120  to a main case  140  of the main body. 
     For example, as shown in  FIG. 1 , one end of the first connection member  310  is coupled to the terminal of the second PCB  150  and one end of the second connection member  320  is coupled to the terminal of the first PCB  130 . Thereafter, when the case  120  is coupled with the main case  140 , the other ends of the first and second connection members  310  and  320  elastically contact the first and second terminal portions  211  and  212  respectively, so as to electrically connect the circuit of the first PCB  130  and the circuit of the second PCB  150  to each other. 
     In this case, one end of the first connection member  310  and one end of the second connection member  320  may be coupled to the terminal of the second PCB  150  and the terminal of the first PCB  130 , respectively by attachment using an adhesive agent. 
     This is the same even in electrical connections between the second line pattern  224 , and the circuit of the first PCB  130  and the circuit of the second PCB  150 . 
     In the exemplary embodiment, the first line pattern body  210  with the first line pattern  214  is manufactured, the first line pattern body frame  230  is formed by insert-injection molding the first line pattern body  210 , and the case frame  120  is formed by insert-injection molding the first line pattern body pattern  230 . However, the second line pattern body  220  with the second line pattern  224  may be manufactured and the second line pattern body  220  may be embedded in the case  120  through operations corresponding to the above operations. 
     As such, in the exemplary embodiment, since the circuit of the first PCB  130  and the circuit of the second PCB  150  are electrically connected with each other by combining the case  120  and the main case  140  with each other, an additional assembly process using a connection medium is not required. Since the line pattern is embedded in the case  120 , an additional space for the connection medium is not required, allowing for the maximal utilization of the space therein. 
       FIG. 8  is a schematic exploded perspective view of a mobile communication terminal which is an electronic device according to another exemplary embodiment of the present invention. 
     In the mobile communication terminal according to another exemplary embodiment of the present invention which is shown in  FIG. 8 , components connected by a transmission line pattern are an antenna embedded in a case and a PCB having a matching circuit. Since other components are substantially the same as those of the electronic device according to the previous exemplary embodiment of the present invention shown in  FIG. 1 , a detailed description of the components will be omitted and hereinafter, differences therebetween will be primarily described. 
     Referring to  FIG. 8 , the mobile communication terminal  100  according to another exemplary embodiment of the present invention may include a line pattern body  240  with a line pattern  244  for transmitting signals, a case  120  in which a radiator  160  with an antenna pattern portion  162  connected to the line pattern body  240  is embedded, and a main case  140  receiving a PCB  170 . 
     The radiator  160  is connected to a first terminal portion  241  formed at one end of the line pattern  244  and is embedded in the case  120 , and signals may be transmitted between the antenna pattern portion  162  of the radiator  160  and the PCB  170  through the line pattern  244 . 
     The line pattern body  240  serves to support the line pattern  244  so as to embed the line pattern  244  in the case  120  and may have a shape corresponding to the shape of the line pattern  244 . 
     In the exemplary embodiment, since a terminal of the antenna pattern portion  162  and a terminal of the PCB  170  are not positioned linearly, the line pattern  244  and the line pattern body  240  are curved. That is, the line pattern  244  and the line pattern body  240  may include a first extension portion extending parallel to a longitudinal direction of the case  120  on the first connection portion  241  connected with the terminal of the antenna pattern portion  162 , a curved portion perpendicularly curved at the end of the first extension portion, and a second extension portion which is curved and extended parallel in the longitudinal direction of the case  120  at the end of the curved portion. 
     The PCB  170  includes a matching circuit for matching the signal transmitted from the antenna pattern  162  or to the antenna pattern portion  162 , and an elastic connection member  350  may be disposed on the terminal  172 . 
     One end of she connection member  350  may be coupled to the terminal  172  and the other end of the connection member  350  may elastically contact the second terminal portion  242  of the line pattern  244 . The connection member  350  may be integrated with the PCB  170  or the line pattern body  240 , and a free end of the connection member  350  may elastically contact the terminal of the PCB  170  or the second terminal portion  242  of the line pattern  244 . 
     A first frame is formed by connecting the radiator  160  having the antenna pattern portion  162  with the line pattern body  240  having the line pattern  244  and insert-injection molding the connected components, and the first frame is also insert-injection molded to form a case frame, thereby manufacturing the case  120 . 
     As described above, in the exemplary embodiment, when the antenna embedded in the case is manufactured, the line pattern can also be manufactured to be connected with the antenna. Thus, an additional process of embedding the line pattern in the case is not required, thereby simplifying the process. 
     As set forth above, in an electronic device and a method for manufacturing the same according to exemplary embodiments of the present invention, a space for connection media connecting spatially separated components or a process for assembling the connection media does not need to be allotted, the utilization efficiency of the internal space of the electronic device is improved. 
     While this invention has been described in connection with what are presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. For example, a configuration in which an additional connection member is attached to a terminal of a PCB is merely illustrative and may be integrated with the PCB, attached to a terminal portion of a line pattern, and integrated with the terminal portion of the line pattern. Accordingly, the scope of the present invention will be determined by the appended claims.
