Abstract: A complex antenna has a first antenna element and a second antenna element each connected at one end to a different feed point and connected to each other at the other end through a parallel resonant circuit. Each antenna element has the same resonant frequency as the parallel resonant circuit. A mobile phone has an antenna switch with a first port connected to the first antenna element, a second port connected to the second antenna element, and a third port that can be connected to one of the first port and the second port and switched therebetween. A signal processing unit causes the antenna switch to connect the third port to the first port or to the second port and detects a signal captured by one of the antenna elements from the output of the third port.

Abstract: A mobile communication terminal including a radio unit for establishing radio communications with radio base stations, a GPS receiving unit for measuring a position of its own, and a control unit. The control unit detects reception condition of radio waves from a radio base station and a distance to the station, selecting the most suitable radio base station to be communicated with based on the detected results.

Abstract: A mobile communication terminal of the present invention comprises a radio unit 2 for establishing radio communications with radio base stations, a GPS receiving unit 4 for measuring a position of its own, and a control unit 5. The control unit 5 detects reception condition of radio waves from a radio base station and a distance to the station, selecting the most suitable radio base station to be communicated with based on the detected results.
