摘要：
In this paper we address the introduction of antenna's radiation pattern agility using an agile metamaterial. We design an agile metamaterial having two different behaviors which can be controlled by an external command. This agile metamaterial is used to design an agile lens which comprises two grids each composed of two regions: the first one constitutes a focusing zone (FZ) and the second one the lens body. The focusing zone parameters-refraction index, size, shape and position in the grid-can be modified using an external switching system (OFF or ON stat); by modifying the FZ parameters one can control the patch antenna's radiation-pattern main-lobe beamwidth and direction (pointing angle) in E- and H-planes.
