Abstract
To provide a novel wireless handset achieving downsized formation and promotion of performance by using independent antennas for transmission and receiving and restraining interference between the antennas for transmission and the antennas for receiving in a communication system. In the communication system, different frequencies for transmission and receiving are simultaneously used, in a wireless handset used in the communication system in which the different frequencies for transmission and for receiving are simultaneously used, a magnetic current antenna for transmission and a magnetic current antenna for receiving are arranged in parallel with each other such that respective magnetic currents are disposed on a straight line.
