Abstract
The purpose of this paper is to study a mechanism of the mutual coupling reduction between two dielectric resonator antenna (DRA) elements by the presence of an artificial magnetic conductor (AMC) ground plane. It is found that the mutual coupling between two DRA elements residing on the AMC ground plane and excited by horizontal probes aligned in the E-plane can be reduced up to 20 dB in comparison to the case of DRAs on the perfect electric conductor (PEC) ground plane and excited by vertical probes aligned in the H-plane. The simulation results are carried out using Ansoft HFSS.
