Portable radio communication device with wide bandwidth and improved antenna radiation efficiency.

摘要

A portable radio communication device capable of eliminating the deterioration of the radiation efficiency due to the occurrence of the dual resonance on the antenna, without reducing the bandwidth. A radio communication device, comprises: a device body (3) made of a conductor body, containing at least one of a radio transmitter and a radio receiver; and an antenna (5), mounted on the device body (3), formed by first and second strip-like conductor elements (5a, 5b) which are connected together at a feeding point (7) connected with said at least one of the radio transmitter and the radio receiver, the first and second strip-like conductor elements (5a, 5b) having an identical electrical length with each other.
