Identifying the appropriate position on the ground plane for MIMO antennas using characteristic mode analysis

Abstract

In this paper, a method for identifying the appropriate position on the ground plane for antennas is proposed based on the current correlation coefficient (C3). This method explains that the mutual coupling between antennas when locating several antennas on the same ground plane is necessary. Given the current distribution on the ground plane induced by each antenna, easily estimating the coupling between antennas is possible. This paper also demonstrates that the proposed method can be used in the design of a multi-input multioutput system. The measured data are in good agreement with the simulation results.
