Abstract

This paper presents a calibration method used to compensate channel amplitude and phase mismatch of the retrodirective antenna array for microwave power transmission. The calibration algorithm of N elements array antenna involves transmission of N time multiplexed orthogonal encoded signals. The received signals are coherently detected, accumulated in vector forms, and a set of correction factors are decoded from the received signal using the inverse of the encoded matrix. A Hadamard matrix is used as the encoding matrix. The demonstration of calibration method is carried out by simulation and analysis.
