PORTABLE RADIO EQUIPMENT

摘要

Disclosed is portable radio equipment wherein a degradation in characteristics caused by electromagnetic coupling between a plurality of antennas is inhibited when three or more antennas and a plurality of radio circuits utilizing radio-frequency bands adjacent to each other are mounted on a case of a limited size. A first antenna (21) and a second antenna (22) are connected with a first radio circuit (31), a third antenna (23) is connected with a second radio circuit (32), and, when the operating frequency band of the second radio circuit (32) is adjacent to a band higher than the operating frequency band of the first radio circuit (31), the feeding point (23a) of the third antenna is located at a position closer to the feeding point (21a) of the first antenna than the feeding point (22a) of the second antenna and, in the operating frequency band of the first radio circuit (31), the gain of the first antenna (21) is set higher than the gain of the second antenna (22) in the low frequency band, and the gain of the first antenna (21) is set higher than the gain of the second antenna (22) in the high frequency band.
