無線通信端末、インピーダンス制御方法およびインピーダンス制御プログラム
Document Type and Number:
Japanese Patent JP5793096
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication terminal, an impedance control method and an impedance control program, capable of adaptively setting impedance to each antenna if situation is different between transmission and reception, without producing extra power loss.SOLUTION: A radio communication terminal 100, having a plurality of antennas, capable of radio communication with a frequency division duplex method includes: a transmission/reception quality information acquisition unit 140 for acquiring transmission/reception quality information of the own terminal; and an impedance control unit 123 for controlling the impedance of a first antenna group 110, based on transmission quality information out of the acquired transmission/reception quality information, and for controlling the impedance of a second antenna group 120 constituted by each antenna not belonging to the first antenna group, based on reception quality information out of the acquired transmission/reception quality information.
