摘要

In this paper, a novel structure for impedance matching in microwave frequency range is introduced. The proposed structure utilizes one or more patterned conducting planes, which are placed transversely in a waveguide. The patterned conducting planes act as frequency selective surfaces for impedance matching purposes. The Green's function of one or more desired patterned planes, considering coupling effects between them, is obtained. Then magnetic field integral equations, in terms of unknown magnetic currents of patterned planes, are calculated and solved using method of moment. The suitable pattern of a patterned plane is obtained using optimization by genetic algorithm, so that the return loss of whole structure, in the desired frequency range vanishes.
