Abstract

The properties of the antenna depend on three structural parameters: the thickness separating the two parallel mirrors, the complex reflectivity of the partially reflective mirror and the radiation of the probes that are distributed between the two mirrors. This shows that a coordinated action on these parameters can lead to a smart EBG antenna. The design of one of the two mirrors constituting the EBG resonator with a smart metamaterial allowing the control of the reflectivity is the key to obtain both a tunable operating frequency and the beam steering adjustment. We show how the feeding antenna can be used to contribute to the beam steering. So we explore the possibility to build smart metamaterials including MEMS or diodes
