     BACKGROUND 
     1. Field of the Disclosure 
     The present disclosure relates generally to a high-frequency transmission circuit included in an electronic device, and more particularly, to a transmission line capable of effectively transmitting a noiseless high-frequency signal in a narrow space without affecting other modules. 
     2. Description of the Related Art 
     Recently, portable terminals having new functions have been rapidly developed and have accounted for a greater part of people&#39;s lives with the common use thereof. 
     Internal circuits of portable terminals are generally implemented on printed circuit boards (PCBs). PCB technologies have been rapidly developing, and flexible PCBs (FPCBs) that can be bent easily are currently used widely, as well as conventional rigid PCBs. 
     In addition, coaxial cables are typically used for high-frequency transmission lines (especially, radio frequency (RF) lines) that are applied to wireless terminals. A large amount of additional material cost may be required to produce coaxial cables used for electronic devices as high-frequency transmission lines, and additional labor cost may be incurred by an increase in the number of assembly steps. In another example, electronic devices have narrow internal spaces available on account of various types of circuit modules mounted therein, and due to the narrow internal spaces, a defect rate may increase when small connectors used for coaxial cables are assembled. 
     SUMMARY 
     An aspect of the present disclosure provides a transmission line capable of effectively transmitting a noiseless high-frequency signal in a narrow space without affecting other modules. 
     Another aspect of the present disclosure provides that a coaxial cable used as a transmission line in a portable terminal can be replaced by a circuit board that includes an FPCB, and thus it is possible to eliminate material costs associated with the manufacture of a coaxial cable. 
     Another aspect of the present disclosure provides a rigid PCB that is disposed between transmission lines of an FPCB, whereby it is possible to reduce line loss occurring in the transmission lines of the FPCB and to provide a high-frequency signal without loss. 
     Another aspect of the present disclosure provides that it is possible to efficiently use a mounting space in a wireless terminal, which enables diversification of the external design of the wireless terminal to improve customer satisfaction. 
     In accordance with an aspect of the present disclosure, a portable communication device includes a housing, a first printed circuit board (PCB) disposed in the housing, a wireless communication circuit mounted on the first PCB, and a second PCB including a connection part connected with the first PCB, a first PCB portion extended from the connection part and having greater flexibility than the connection part, a second. PCB portion extended from the first PCB portion and having less flexibility than the first PCB portion, a third PCB portion extended from the second PCB portion and having greater flexibility than the second PCB portion, a fourth PCB portion extended from the third PCB portion and having less flexibility than the first PCB portion, a signal line extended to the connection part along the first, second, third, and fourth PCB portions, and vias arranged in at least a partial area of the second PCB portion or the fourth PCB portion, wherein a portion of the signal line is located between some of the vias.

     Hereinafter, various embodiments of the present disclosure are described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure is intended to be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In the description of the accompanying drawings, similar reference numerals may be used to designate similar elements. 
     As used herein, the expressions “have”, “may have”, “include”, or “may include” refer to the existence of a corresponding feature (e.g., numeral, function, operation, or element such as a component), and do not exclude one or more additional features. 
     In the present disclosure, the expressions “A or B”, “at least one of A and/or B”, and “one or more of A and/or B” may include all possible combinations of the items listed. For example, the expressions “A or B”, “at least one of A and B”, and “at least one of A or B” refer to all of (1) including at least one A, (2) including at least one B, and (3) including all of at least one A and at least one B. 
     The expressions “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance of the components but are not intended to limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure. 
     It should be understood that when an element (e.g., a first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., a second element), the element may be directly connected or directly coupled to the other element or any other element (e.g., a third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., a first element) is referred to as being “directly connected,” or “directly coupled” to another element (e.g., a second element), there is no element (e.g., a third element) interposed between them. 
     The expression “configured to” used in the present disclosure may be used interchangeably with the expressions, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, and “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware.

     The first and second PCBs  310  and  320  according to an embodiment of the present disclosure may be formed of a plurality of layers, and the plurality of layers may include one or more conductive layers  306  in  FIG.  2    described below and one or more insulation layers  303 . 
     The first PCB  310  in  FIG.  1    according to an embodiment of the present disclosure may be a rigid PCB. The first PCB  310  may be electrically connected to the second PCB  320  through a connector  370 .

An antenna contact member (for example, a C-clip) or an RF component (for example, a matching circuit) may be mounted on the interconnection pad  394 . 
     The second PCB  320  according to an embodiment of the present disclosure may be connected to the first PCB  310  and may include an FPCB  330  or a rigid PCB  340 . The FPCB  330  and the rigid PCB  340  of the second PCB  320  may be integrated with each other. For example, a first FPCB  331 , a first rigid printed circuit board  341 , a second flexible printed circuit board  332 , and a second rigid PCB  342  may be arranged in sequence. The second rigid PCB  342  may include an antenna connector and a universal serial bus (USB) connector, for example. 
     The second PCB  320  according to an embodiment of the present disclosure may have the electrical path  350  therein through which electrical signals can be transmitted. The electrical path  350  may be connected with the first PCB  310  through the FPCB  330  and the rigid PCB  340 , which are integrated with each other. 
     The electrical path  350  according to an embodiment of the present disclosure may extend from a first electrical component  230  in  FIG.  10    described below to a second electrical component  240  and may be disposed on or in the PCB  300  in  FIG.  1   . The electrical path  350  may be implemented as a transmission line of a side-guarded micro-strip-line type or a strip-line type, where the transmission line is shielded by a ground line  360  in order to transmit a high-frequency signal, which may be, for example, an RF signal. 
     The electrical path  350  according to an embodiment of the present disclosure, which is disposed on or in the second PCB  320 , may receive a high-frequency signal through the connector  370  and may forward the received signal to antenna radiators  231  and  232  in  FIG.  10    described below. Furthermore, a plurality of electrical paths  350  in  FIG.  1    may be provided, and a ground line  360  may be disposed between the electrical paths  350  so that the electrical paths  350  can independently transmit the high-frequency signal without mutually affecting the characteristics thereof. 
     The ground line  360  according to an embodiment of the present disclosure may be disposed adjacent to the electrical path  350 , and conductive vias  305  may be arranged in a portion of the area of a ground line  360 ( a ). Accordingly, the electrical path  350  can pass through the PCB  300  without making contact with the conductive vias  305 . 
     According to an embodiment of the present disclosure, the connector  370  for connecting the electrical path  350  may be disposed between the first and second PCBs  310  and  320  in order to transmit a high-frequency signal therebetween.

Furthermore, for example, the pin map of a transmission line included in the connector  370  may be implemented in the sequence of a ground, an RF signal, and a ground. 
     Hereinafter, the plurality of layers and the conductive vias  305  of the PCB  300  is described in detail. 
       FIG.  2    is a partial sectional view of the plurality of layers of the PCB of  FIG.  1   , according to an embodiment of the present disclosure, where  FIG.  2    is taken along line B-B′ of  FIG.  1   . Hereinafter, the PCB is described as the second PCB  320 . However, the following description may be applied to second printed circuit boards  420 ,  520 ,  620 , and  720  in other embodiments, which will be described below. 
     Referring to  FIG.  2   , the second printed circuit board  320  according to an embodiment of the present disclosure may be formed of a plurality of layers, each including at least one conductive layer  306 , at least one first insulation layer  302 , and at least one second insulation layer  303 . The conductive layer  306  and the first insulation layer  302  may be included in a flexible copper clad laminated (FCCL) layer. Further, the first insulation layer  302  may include polyimide. 
     The conductive layers  306  according to an embodiment of the present disclosure are arranged in the stacking direction, and the first insulation layer  302  is disposed on the rear or front surface of each conductive layer  306 . The individual layers may be alternately arranged. One or more conductive vias  305  may be formed to electrically connect the conductive layers  306 . 
     According to an embodiment of the present disclosure, the second insulation layer  303  is provided between the conductive layers  306  to prevent the conductive layers  306  from being electrically connected together through contact therebetween. For example, the plurality of second insulation layers  303  disposed between the plurality of conductive layers  306  may function to insulate the layers and may include a resin and a glass fabric. 
     According to an embodiment of the present disclosure, a plurality of electronic components may be disposed on and electrically connected to the conductive layers  306 . The electronic components may be electrically connected to the antenna radiators  231  and  232  in  FIG.  10    described below provided in the electronic device. For example, the electronic components may include an antenna clip, a connector, and a switch device. 
     Without being limited thereto, however, various materials capable of passing electricity therethrough, other than metal, may be applied to the conductive layers  306  in  FIG.  2   . 
     According to an embodiment of the present disclosure, the conductive layers  306  may be electrically connected to any of a plurality of signal lines and ground lines. 
     The conductive layers  306  according to an embodiment of the present disclosure may be provided, on the top and bottom thereof, with a protective layer  301  capable of protecting the conductive layers  306 . The protective layers  301  may be formed of an insulating coating material, such as solder resist, and, for example, a photo imagable solder resist ink (PSR ink) may be used for the solder resist. The PSR ink may be left on a product because it provides insulation and protection even after a component is mounted. Accordingly, the protective layers  301  coated on the exterior of the conductive layers  306  can prevent a short circuit, a connection, corrosion, and contamination of a circuit during a manufacturing process and can protect the conductive layers  306  from external shock, humidity, and chemical substances after the manufacturing process. 
     The conductive vias  305  according to an embodiment of the present disclosure, which electrically connect the conductive layers  306 , may include a first conductive via  305 ( a ) capable of electrically connecting all the layers and a second conductive via  305 ( b ) capable of electrically connecting adjacent layers. For example, the first conductive via  305 ( a ) may be formed by computerized numerical control (CNC) hole machining and copper plating, and the second conductive via  305 ( b ) may be formed by laser hole machining and copper plating. 
     The conductive vias  305  according to an embodiment of the present disclosure may include a region that forms a predetermined pattern within the PCB  300 . The conductive vias  305  may be configured to make contact with at least one of the conductive layers  306  and to pass through at least one of the multiple layers. 
     A pattern cover layer  304  according to an embodiment of the present disclosure may be disposed in a single layer on the bottom or top of the conductive layers  306  while surrounding a pattern and thus can protect the internal pattern. For example, the pattern cover layer  304  may be formed of polyimide (PI) and an adhesive. 
     According to an embodiment of the present disclosure, rigid PCBs  380  and  382  and a FPCB  381  may be integrated with one another. The FPCB  381  may not include the second insulation layer  303 , but may include the pattern cover layer  304  instead of the protective layer  301 . 
       FIG.  3    is a sectional view of an interlayer configuration of a plurality of layers of the PCB of  FIG.  1   , according to an embodiment of the present disclosure, where  FIG.  3    is taken along line B-B′ of  FIG.  1   . 
     Referring to  FIG.  3   , the second PCB  320  may include the first FPCB  331 , the first rigid PCB  341 , and the second FPCB  332 , which are integrally connected together. 
     Further, the second PCB  320  may include first to fourth ground pattern layers  371 ,  372 ,  373 , and  374  that are connected by the conductive vias  305  in order to form a ground. The entirety of the first and second ground pattern layers  371  and  372  forms a ground. Only a part of the second and third ground pattern layers  372  and  373  forms a ground. According to an embodiment of the present disclosure, there may be a layer having no ground layer. 
     Signal line patterns  364  not connected to the ground may be provided. These signal line patterns  364  may be used as RF signal lines. 
     The ground pattern layers according to an embodiment of the present disclosure may be connected by the first conductive via  305 ( a ) capable of electrically connecting all of the layers and the second conductive via  305 ( b ) capable of electrically connecting adjacent layers. For example, all or some of the ground pattern layers may be connected using the first conductive via  305 ( a ) passing through all of the layers. For example, the first to fourth ground pattern layers  371 ,  372 ,  373 , and  374  may be connected by the first conductive via  305 ( a ). The adjacent ground pattern layers may be connected to each other by the second conductive via  305 ( b ). For example, the first and second ground pattern layers  371  and  372  may be connected to each other by the second conductive via  305 ( b ). 
     According to an embodiment of the present disclosure, a PCB (for example, the PCB  300  of  FIG.  1   ) may include the first PCB  310  and the second PCB  320  including a rigid PCB and a FPCB. In this case, the PCB is described as the PCB  300  of  FIG.  1    as an example, but may be applied to the PCBs  400 ,  500 ,  600 , and  700  of  FIGS.  4 ,  5 ,  6 A ,  6 B,  6 C,  7 A,  7 B, and  7 C. 
     According to an embodiment of the present disclosure, the high-frequency transmission line provided by the PCB in the electronic device may be configured such that the FPCB  330  having advantages of reducing a material cost and ensuring a mounting space can substitute for a coaxial cable. 
     For example, the first and second FPCBs  331  and  332  may be used between the second rigid PCB  342  and the first PCB  310  in order to transmit a high-frequency signal from the second rigid PCB  342  to the first PCB  310 . 
     In another example, in order to eliminate loss that occurs when a high-frequency signal is transmitted using the FPCB  330 , the first rigid PCB  341  may be disposed between the first and second FPCB  331  and  332 , and the ground pattern layers may be connected by the conductive vias  305 . 
     According to an embodiment of the present disclosure, in order to mitigate an increase in line loss, the electronic device may further include a section containing the first rigid PCB  341  in the middle of the FPCB  330 . If the FPCB  330  has a length of 10 mm or more, the transmission line in the section may cause a great line loss. For example, the transmission line may have a change in the strip line characteristics due to the inductance generated by the ground lines  360  disposed on the opposite sides thereof, and thus the line loss generated by the electrical path  350  may increase markedly. 
     According to an embodiment of the present disclosure, the electronic device may have the one or more vias  305  arranged on the first rigid PCB  341 . When the grounds are connected by the conductive vias  305  arranged on the first rigid PCB  341 , the inductance generated by the ground lines  360  can be reduced, for example, by virtue of the interlayer ground connection on the ground lines  360 , thereby reducing adverse effects, such as line loss. Furthermore, an all-ground layer (ground line) is disposed between the layers providing the second PCB  320 , and the entire ground line  360  may be connected to the all-ground layer through the conductive vias  305 , whereby it is possible to have a much greater line loss reduction effect. 
     According to an embodiment of the present disclosure, a rigid PCB may be disposed between the FPCBs, thereby preventing the layers from being separated or twisted as described above. In the case where the existing FPCBs are installed on a drive unit, the layers of the FPCBs may be separated or twisted. Even in this case, there may be a change in the characteristics of a strip line, which may cause line loss in the transmission line or other adverse property changes. 
     However, an electronic device having the aforementioned arrangement is advantageous in that the side effects mentioned above are not exhibited even when the FPCBs move, whereby it is possible to reduce line loss in the transmission line and to alleviate other adverse characteristics. 
     In addition, in the case where a transmission line has a greater length, it is possible to solve shortcomings, such as line loss, by additionally placing rigid PCBs in several positions on the FPCBs and using a connection between the ground line  360 , other ground pattern layers  363 , and the conductive vias  305 .

     The electrical path  550  according to an embodiment of the present disclosure, which is disposed on or in the second PCB  520 , may receive a high-frequency signal through the connector  570  and may forward the received signal to an antenna radiator.

     The ground line  560  according to an embodiment of the present disclosure may be disposed adjacent to the electrical path  550 , and conductive vias  505  may be arranged in a portion of the area of the ground line  560 . Accordingly, the electrical path  550  can pass through the PCB  500  without making contact with the conductive vias  505 . 
     A plurality of layers of the PCB  500  and the conductive vias  505  are the same as those in an above-described embodiment with reference to  FIGS.  1  to  3   , and therefore descriptions thereof are omitted here. 
       FIGS.  6 A,  6 B, and  6 C  are front views of conductive vias according to an embodiment of the present disclosure, the conductive vias being arranged in electronic device PCBs.  FIGS.  6 A,  6 B, and  6 C  illustrate various forms of PCBs. 
     Referring to  FIG.  6 A , a second PCB  620  according to an embodiment of the present disclosure may include an FPCB  630  and a rigid PCB  640 , which are integrated with each other. For example, the second PCB  620  may include a first FPCB  631 , the first rigid PCB  640 , and a second FPCB  632 , which are arranged in sequence. 
     An electrical path  650  according to an embodiment of the present disclosure may be disposed on or in the second PCB  620  and may be implemented to be a transmission line of a side-guarded micro-strip-line type or a strip-line type in order to transmit a high-frequency signal. 
     The electrical path  650  according to an embodiment of the present disclosure, which is disposed on or in the second PCB  620 , may receive a high-frequency signal through a connector and may forward the received signal to an antenna radiator. Furthermore, a plurality of electrical paths  650  may be provided, and a ground line  660  may be disposed between the electrical paths  650  so that the electrical paths  650  can independently transmit the high-frequency signal without mutually affecting the characteristics thereof. 
     The ground lines  660  according to an embodiment of the present disclosure may be disposed adjacent to the electrical path  650  and may be connected with one or more conductive layers through conductive vias  605 ( c ) in the PCB. Since the conductive vias  605 ( c ) are arranged in one ground line  660 , the electrical path  650  may pass through the PCB without making contact with the conductive vias  605 ( c ). 
     The electrical path  650  according to an embodiment of the present disclosure is disposed to pass through the flexible PCB  630  and the rigid PCB  640 , and thus the ground lines  660  disposed on opposite sides of the electrical path  650  may also be disposed to pass through the FPCB  630  and the rigid PCB  640 . While two ground lines  660  are provided in  FIG.  6 A , the number of ground lines  660  may be diversely varied so as to avoid contact with the electrical path  650 , without being limited thereto. 
     For example, the first ground line  660 ( a ) disposed on the left side may have a greater width than the second ground line  660 ( b ) disposed on the right side, and the plurality of conductive vias  605 ( c ) may be formed in the region where the rigid PCB  640  and the ground line  660 ( a ) cross each other. The second ground line  660 ( b ) may not include the conductive vias  605 ( c ) since the second ground line  660 ( b ) has a lesser width than the first ground line  660 ( a ). 
     The PCB is illustrated as having the conductive vias  605 ( c ) arranged in the first ground line  660 ( a ) having a great width. The conductive vias  605 ( c ) arranged in the first ground line  660 ( a ) may include vias passing through all layers. Ground patterns in all or some of the layers and the ground line on a side of the electrical path may be connected by the conductive vias  605 ( c ) passing through all the layers. 
     Referring to  FIG.  6 B , ground lines  660  may be separately disposed on opposite sides of an electrical path  650  in the second PCB  620  and may be formed to pass through the flexible PCB and the rigid PCB along the lengthwise direction of the electrical path  650 . While the two ground lines  660  are provided in  FIG.  6 B , the number of ground lines  660  may be diversely varied so as to avoid contact with the electrical path  650 , without being limited thereto. 
     According to an embodiment of the present disclosure, the first ground line  660 ( a ) disposed on the left side may have a greater width than the second ground line  660 ( b ) disposed on the right side, and a plurality of conductive vias  605 ( c ) may be formed in the region where the first ground line  660 ( a ) and the rigid PCB  640  cross each other. The second ground line  660 ( b ) on the right side may not include the conductive vias  605 ( c ) having the size since the second ground line  660 ( b ) has a lesser width than the first ground line  660 ( a ). Instead, the second ground line  660 ( b ) on the right side may have conductive vias  605 ( d ) having a lesser size than the conductive vias  605 ( c ). 
     For example, the rigid PCB  640  formed of a plurality of layers may include the third conductive vias  605 ( c ) passing through all of the layers in the PCB and the fourth conductive vias  605 ( d ) passing through some of the layers. The third conductive vias  605 ( c ) may have a greater hole size than the fourth conductive vias  605 ( d ) passing through some of the layers, and may be arranged in the ground line  660 ( a ) having a great width. However, the fourth conductive vias  605 ( d ) may be arranged in the second ground line  660 ( b ) having a lesser width and disposed on the right side, since the fourth conductive vias  605 ( d ) have a lesser hole size than the third conductive vias  605 ( c ). Even when the ground lines  660  are connected with a ground in a different layer through some conductive vias  605 , it is possible to reduce line loss. 
     Referring to  FIG.  6 C , ground lines  660  may be separately disposed on opposite sides of an electrical path  650  and may be formed in the lengthwise direction of the electrical path  650 . While two ground lines  660  are provided in  FIG.  6 C , the number of ground lines  660  may be diversely varied so as to avoid contact with the electrical path  650 , without being limited thereto. 
     According to an embodiment of the present disclosure, the first ground line  660 ( a ) disposed on the left side may have a lesser width than the second ground line  660 ( b ) disposed on the right side, and a plurality of conductive vias  605 ( d ) may be formed in the region where the second ground line  660 ( b ) and the rigid PCB  640  cross each other. The second ground line  660 ( b ) on the right side has a greater width than the first ground line  660 ( a ), but is too narrow to have the great conductive vias  605 ( c ). Instead, the conductive vias  605 ( d ) having a lesser width may be arranged in the second ground line  660 ( b ) on the right side. 
     Therefore, according to an embodiment of the present disclosure, the second ground line  660 ( b ) having a lesser width and disposed on the right side may electrically connect the PCB using the fourth conductive vias  605 ( d ) passing through some layers. Even when the ground lines  660  are connected with a ground in a different layer through some of the fourth conductive vias  605 ( d ), it is possible to reduce line loss. 
       FIGS.  7 A,  7 B, and  7 C  are top views illustrating conductive vias arranged in PCBs according to an embodiment of the present disclosure.  FIGS.  7 A,  7 B, and  7 C  illustrate various forms of PCBs. 
     Referring to  FIG.  7 A , a second PCB  720  may include a plurality of FPCBs and/or a plurality of rigid PCBs. For example, the second PCB  720  may be configured such that FPCBs  730  and rigid PCBs  740  are alternately disposed and are integrated with each other.

For example, the second PCB  720  may include the first FPCB  731 , the first rigid PCB  741 , the second FPCB  732 , the fifth rigid PCB  742 , and the third FPCB  733 , which are arranged in sequence. 
     The first and fifth rigid PCBs  741  and  742  may be disposed to be spaced apart from each other and may include a plurality of conductive vias  705 ( c ) and ground lines  760 . 
     An electrical path  750  according to an embodiment of the present disclosure may be disposed on or in the second PCB  720  and may be implemented to be a transmission line of a side-guarded micro-strip-line type or a strip-line type in order to transmit a high-frequency signal. 
     The electrical path  750  according to an embodiment of the present disclosure, which is disposed on or in the second PCB  720 , may receive a high-frequency signal through a connector and may forward the received signal to an antenna radiator. Furthermore, a plurality of electrical paths  750  may be provided, and the ground line  760  may be disposed between the electrical paths  750  so that the electrical paths  750  can independently transmit the high-frequency signal without mutually affecting the characteristics thereof. 
     The ground lines  760  according to an embodiment of the present disclosure may be disposed adjacent to the electrical path  750  and may be connected with one or more conductive layers through the conductive vias  705 ( c ) in the PCB  720 . 
     The ground lines  760  according to an embodiment of the present disclosure may be formed to pass through the FPCB  730  and the rigid PCBs  740  along the lengthwise direction of the electrical path  750 . While two ground lines  760  are provided in the present disclosure, the number of ground lines  760  may be diversely varied so as to avoid contact with the electrical path  750 , without being limited thereto. 
     For example, the first ground line  760 ( a ) disposed on the left side of the first and fifth rigid PCBs  741  and  742  may have a greater width than the second ground line  760 ( b ) disposed on the right side, and the plurality of conductive vias  705 ( c ) may be formed in the regions where the first ground line  760 ( a ) crosses the first and fifth rigid PCBs  741  and  742 . In another example, the second ground line  760 ( b ) on the right side may not include the conductive vias  705 ( c ) having the size since the second ground line  760 ( b ) has a lesser width than the first ground line  760 ( a ). The PCB is illustrated as having the conductive vias  705 ( c ) arranged in the first ground line  760 ( a ) having a great width. 
     Referring to  FIG.  7 B , the second PCB  720  may include the FPCBs  730  and the rigid PCBs  740  that are integrated with each other. For example, the second. PCB  720  may be configured such that the FPCBs  730  and the rigid PCBs  740  are alternately disposed and are integrated with each other. 
     The second PCB  720  according to an embodiment of the present disclosure may include the first FPCB  731 , the first rigid PCB  741 , the second FPCB  732 , the fifth rigid PCB  742 , and the third FPCB  733 , which are arranged in sequence. 
     Ground lines  760  according to an embodiment of the present disclosure may be separately disposed on opposite sides of the electrical path  750  and may be formed along the lengthwise direction of the electrical path  750 . While two ground lines  760  are provided in the  FIG.  7 B , the number of ground lines  760  may be diversely varied so as to avoid contact with the electrical path  750 , without being limited thereto. 
     According to an embodiment of the present disclosure, the first ground line  760 ( a ) disposed on the left side of the first and fifth rigid PCBs  741  and  742  may have a greater width than the second ground line  760 ( b ) disposed on the right side, and a plurality of conductive vias  705 ( c ) may be formed in the regions where the first ground line  760 ( a ) crosses the rigid PCBs  740 . However, the second ground line  760 ( b ) on the right side may not include the conductive vias  705 ( c ) having the size since the second ground line  760 ( b ) has a lesser width than the first ground line  760 ( a ). Instead, the second ground line  760 ( b ) on the right side may have conductive vias  705 ( d ) having a lesser size than the conductive vias  705 ( c ). 
     For example, the rigid PCBs  740  formed of a plurality of layers may include the third conductive vias  705 ( c ) passing through all the layers in the PCB and the fourth conductive vias  705 ( d ) passing through some of the layers. The third conductive vias  705 ( c ) may have a greater hole size than the fourth conductive vias  705 ( d ) passing through some of the layers, and may be arranged in the ground line  760 ( a ) having a great width. However, the fourth conductive vias  705 ( d ) may be arranged in the second ground line  760 ( b ) having a lesser width and disposed on the right side, since the fourth conductive vias  705 ( d ) have a lesser hole size than the third conductive vias  705 ( c ). Even when the ground lines  760  are connected with a ground in a different layer through some conductive vias  705 , it is possible to reduce a line loss. 
     Referring to  FIG.  7 C , the second PCB  720  may include the FPCBs  730  and the rigid PCBs  740  that are alternately disposed and are integrated with each other. In this embodiment, at least two rigid PCBs  740  may be provided between the FPCBs  730 . For example, the second PCB  720  may include the first FPCB  731 , the second FPCB  732 , the first rigid PCB  741 , the fifth rigid PCB  742 , and the third FPCB  733 , which are arranged in sequence. 
     Ground lines  760  according to an embodiment of the present disclosure may be separately disposed on opposite sides of the electrical path  750  and may be formed along the lengthwise direction of the electrical path  750 . While two ground lines  760  are provided in the present disclosure, the number of ground lines  760  may be diversely varied so as to avoid contact with the electrical path  750 , without being limited thereto.

     The first antenna  231  may support LB and H/MB bands, and the second antenna  232  may support an H/MB band. According to an embodiment of the present disclosure, an LB band has a relatively great wavelength so that an antenna may have a relatively great size, and there may be a mounting space limitation by adding an antenna supporting multiple LBs to the main part  210  of the terminal. Therefore, only one antenna may be configured to support an LB band. 
     In the case where the electronic device  10  additionally has the diversity part  220  according to an embodiment of the present disclosure, the electronic device  10  may include the third and fourth antennas  233  and  234 .

     By virtue of the structure described above, the electronic device  10  can receive signals using four antennas in an H/MB band and can receive signals using two antennas in an LB band. That is, 4th order diversity/MIMO can be performed in an H/MB band, and 2nd order diversity/MIMO can be performed in an LB band.
