In this paper we study the influence of metamaterials on the performances of an array of 2 × 4 microstrip patch antenna operating at about 10 GHz. For this purpose, metamaterials are based on Artificial Magnetic Conductor (AMC) and on inductive and capacitive planar structures. These structures providing High Impedance Surfaces (HIS) and Partially Reflective Surfaces (PRS). Application of these structures allows to improve the performance of antenna, increase the gain and offer a good directivity.
