Abstract
Cavity-backed slot (CBS) antennas are commonly used in earth-based and space-borne MIMO systems. Coupling between antennas degrades the performance of MIMO systems. Therefore, it is desirable to minimize the coupling between antennas used on MIMO systems. In this paper, the finite-difference time-domain (FDTD) method is used to analyze antenna coupling with emphasis on different methods to reduce coupling. Specifically, coupling reduction is attempted using lossy material superstrates or ground plane discontinuities, such as slits.
