 Identifying the Appropriate Position on the Ground Plane for MIMO Antennas Using Characteristic Mode Analysis Jusun Won1, Sinhyung Jeon2, Sangwook Nam1 1School of Electrical Engineering and Computer Science, Institute of New Media and Communications, Seoul National University2DMC R&D Center, Samsung Electronics Correspondence:  Jusun Won,Email: nexus@ael.snu.ac.kr 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 ($C^3$). 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 multi-output system. The measured data are in good agreement with the simulation results.
