Further, the cylindrical portion 604a of the hinge portion 604 is inserted and fitted between the upper right edge portion 103q of the lower housing 103 and the protruding cylindrical portion 103r, and the leg portion 604b of the hinge portion 604 is the upper second housing portion 102b. The screw 114 is inserted into the circular hole 604h and fixed by the screw 114. A connection point 111 of the wireless communication circuit 110 is connected to the fitting cylindrical member 606 via an antenna element 605 provided to extend inside the lower housing 103, and a connection point 609 of the wireless communication circuit 110 is connected to the lower housing. It is connected to the fitting cylindrical member 608 through an antenna element 607 provided to extend inside the body 103.

  In the portable wireless communication device configured as described above, the connection point 111 of the wireless communication circuit 110 is connected to the upper first housing portion 102a via the antenna element 605, the fitting cylindrical member 606, the hinge portion 603, and the screw 113. The connection point 609 of the wireless communication circuit 110 is electrically connected to the upper first housing portion 102a via the antenna element 607, the fitting cylindrical member 608, the hinge portion 604, and the screw 114. Yes. Here, the circuit from the antenna element 605 to the upper first casing portion 102a and the circuit from the antenna element 607 to the upper first casing portion 102a constitute the first antenna element 102A. In the present embodiment, as shown in FIG. 13, the antenna element 102A is connected to a reactance element 610 or 611 having reactance values Xa and Xb different from each other via a connection point 609 and a switch SW2 controlled by the controller 150.

Since the reactance value changes, the resonance frequency of the antenna element 120A changes. Accordingly, the operating frequency can be switched in a time division manner, for example, between transmission and reception. Alternatively, for example, the reactance elements 610 and 611 may be selectively switched by switching the switch SW2 to the contact a side or the contact b side according to the open state and the closed state of the portable wireless communication device. Thereby, depending on the open state and the closed state of the portable wireless communication device, the state of the object located in the vicinity of the antenna element 102A changes, and the reactance elements 610 and 611 are selectively switched according to these states.

Alternatively, when switching to the contact b side, the reactance value connected to the antenna element 102A changes. That is, since the electrical length of the antenna element 102A that operates as a non-excitation element for the antenna device 901 to be operated can be changed, the directivity characteristics of the entire antenna device can be changed.

  In the embodiment of FIG. 13, the two reactance elements 610 and 611 are selectively switched. However, the present invention is not limited to this, and three or more reactance elements may be selectively switched.

Modified example.
FIG. 43 is a longitudinal sectional view showing a detailed configuration of a boom unit 910 of a portable wireless communication apparatus according to another modification of the embodiment of the present invention. In FIG. 43, the first conductor antenna element layer 911 is formed on the upper surface of the boom part 901, while being separated from the conductor antenna element layer 911, the second conductor is formed on the lower surface of the boom part 901. The antenna element layer 912 is formed, and the two conductor antenna element layers 911 and 912 are electrically connected by the connection point 913 in the lower housing 103 and further connected to the connection point 902.

  In the portable wireless communication device configured as described above, the first conductor antenna element layer 911 is formed with an electrical length that resonates in a lower frequency band (for example, 800 MHz band), and the second conductor antenna element layer 912 is further formed. If it is formed with an electrical length that resonates in a high frequency band (for example, 1.5 GHz band), the lower the frequency, the closer the electrical distance. In general, when the distance between the ground conductor of the printed wiring board 106 in the lower housing 103 and each of the conductor antenna element layers 911 and 912 is the same, the antenna gain is lower in the conductor antenna element layer in the lower frequency band. To do. However, as shown in FIG. 43, by disposing the lower frequency band on the outside (upper side) separated from the ground conductor, the distance from the ground conductor of the lower housing 103 can be increased. Since the capacitive coupling between the conductor antenna element layer 911 and the ground conductor can be reduced, the input impedance when the antenna device is viewed at the feeding point can be further reduced, and for example, impedance matching of 50Ω can be easily taken. In addition, using the two conductor antenna element layers 911 and 912, a wide band and high gain antenna characteristic can be realized.

  In the above embodiment, when the boom part 910 is made of a conductive material such as magnesium or zinc, the mechanical strength of the boom part 910 can be increased, and when the portable wireless communication device falls on the ground such as the floor. It can be prevented from being damaged. In addition, since at least a part of the boom portion 910 is formed by being filled with a dielectric material, there is an effect of lowering the resonance frequency of the antenna element 901 in the boom portion 910, compared with a case where no dielectric material is filled. Can be downsized. Furthermore, by fixing the periphery of the antenna element 901 with a dielectric material such as resin, the mechanical strength of the boom portion 910 and the antenna element 901 can be increased, and mass productivity can be further increased.

  In the above embodiment, at least a part of the boom part 910 may be made of an elastic or flexible resin material such as an elastomer.

  As described above, according to the foldable portable wireless communication apparatus according to the present embodiment, at least a part of the upper housing or the lower housing also serves as an antenna element, and is resistant to impacts such as dropping. In addition to the effect of strengthening, since an occupied space as an antenna element is not required, the number of parts can be reduced and the portable wireless communication device can be made thinner and lighter than the conventional technology. Further, by causing the hinge portion made of a conductive material to function as a part of the antenna device, the size of the antenna device can be increased and the antenna gain can be improved. Furthermore, by sticking a thin insulating sheet 301 made of a dielectric material or a magnetic material to the surface of the upper first housing portion 102a, the distance between the human body and the antenna device can be increased, so that during a call It is possible to reduce a decrease in antenna gain due to electromagnetic influence of the human body.
