Abstract

Mutual coupling effect between antennas on MIMO (multiple input multiple output) transmission is an important factor to take into account for an accurate modelling channel when antennas are closely spaced. The aim of this paper is to present the impact of mutual coupling on MIMO channel characteristics according to several propagation contexts. To achieve this purpose an original study, which has recourse to two complementary simulation methods, is set out. The first method simulates multipath propagation channel thanks to an optimized 3D ray-tracing. The second one is derived from rigorous electromagnetic analysis based on a method of moments. It models, in near field, mutual coupling between antennas. Results illustrate this impact on MIMO channel transfer matrix.
