Influence of metamaterial surface impedance on patch antenna coupling

A method of antenna element coupling control using a readjust of the surface impedance of the plane, it is mounted, is shortly described. A construction of a tunable frequency-selective metamaterial-made surface, which is designed to be a patch antenna element ground plane, is presented. Results of antenna VSWR measurements, which show the coupling change correspondingly the antenna ground plane surface impedance tuning, are shown.
