Mutual coupling reduction between dual polarized microstrip patch antennas using compact spiral Artificial Magnetic Conductor

A bstract—In this paper, we present a dual polarized microstrip antenna above an Artificial Magnetic Conductor (AMC). It is printed on a high permittivity substrate (εr=9.82). The AMC is used in order to reduce the mutual coupling between two radiating elements. Two experimental prototypes are realized in order to validate the analysis. First, the performances of a patch antenna above
