Abstract (in Japanese) (See Japanese page) 
(in English) The input impedance of the antenna fluctuates because of various usage conditions, which causes a mismatch between an internal circuit and an antenna. An automatic matching system solves this problem, then this report presents a reconfigurable impedance tuner which has a set of fixed capacitors controlled by switching p-i-n diodes. The fast control algorithm to select the proper tuner impedance condition is proposed and it is mounted on FPGA to demonstrate the performance.
