ティ用サブアンテナとして使用される。FIG. 11 is a perspective view showing an example of a conventional portable wireless device disclosed in Japanese Patent Laid-Open No. 11-177485. The portable wireless device illustrated in FIG. 11 includes an upper housing 101 including a receiver 103 and a display portion 105, a lower housing 102 including a microphone 104 and an operation portion 109, and the upper housing 101 and the lower portion during communication. The case 102 is opened and used, and is carried (standby) with the upper case 101 and the lower case 102 closed. A diversity main antenna 106 for both transmission and reception is arranged in the upper housing 101, and the upper housing 10
l, the lower housing 102 has first and second antennas 107 and 108 as sub-antennas for diversity, respectively.
Is installed. When the upper housing 101 and the lower housing 102 are open (during communication), the second sub-antenna is used as a second diversity sub-antenna.
When the upper housing 101 and the lower housing 102 are closed, the first antenna 108 is selected as the diversity sub-antenna.
Antenna 107 is selected. Therefore, during communication, the second antenna 108, which is located away from the human body (head), is used as a sub-antenna for diversity, and when not in a call, that is, when the upper housing 101 and the lower housing 102 are folded. Assuming that the first antenna 107 is placed on a desk or the like, the first antenna 107 located at a position apart from the desk is used as a sub antenna for diversity.

る。In recent years, it has been strongly desired that not only voice but also data, images, etc. are communicated in a portable radio device in recent years, and when a voice call is made even during communication,
There are various cases where data communication is performed and when a typical videophone for voice + data communication is performed. The positional relationship between the portable wireless device and the human body in such various communication states is often used by holding it by hand in addition to the case where it is used in the vicinity of the human body head as usual even during communication. Exists. For example, in the conventional example shown in FIG. 11, when data communication is performed, the lower housing is held by hand and the communication is performed while looking at the display unit. However, there was a point that was deteriorated.
Also, due to its portability, there is a demand for a transmitter antenna with a built-in type to eliminate the antenna protrusion, but the built-in type antenna is closer to the human body than the external antenna, and the antenna sensitivity deteriorates. Human exposure to radiation (SAR) increases. Therefore, it is necessary to increase the distance between the human body and the antenna in actual use, and it is difficult to reduce the size and thickness of the wireless device.
