Summary :

The input impedance of an 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 paper presents a reconfigurable impedance tuner that has a set of fixed capacitors controlled by switching p-i-n diodes. A fast control algorithm for selecting the appropriate conditions of an impedance tuner is proposed and mounted on FPGA to demonstrate the performance.
