Design of matching networks based on image impedances for near field MIMO

Abstract

This paper proposes matching method based on image impedances for near field MIMO. In this letter, matching method, which can realize matching of all port at the same time by extending image impedances theory, is proposed. Numerical analysis and experimental results demonstrate the proposed matching method is effective in enhancing the channel capacity of the near field MIMO, where facing antennas strongly couple to each other.
