Mutual coupling reduction of antennas on a complex superstructure

Abstract

A useful method for mutual coupling reduction of antennas on complex superstructure is proposed. The best position and direction of the victim antenna with respect to the causative antenna are obtained by a genetic algorithm (GA) and a matrix Green's function. The MoM solver is used to achieve coupling factors such as Z(21) and S-21 between two antennas. Matrix Green's function allows us to procure an immediate result for position and direction change of the victim antenna.
