Abstract

Multiple-layer optimized periodic surfaces are proposed for the design of broadband Fabry-Perot high gain antennas. Three layers of periodic arrays of metallic square patche are used, printed on a dielectric substrate and placed in front of a ground plane, forming three air cavities. The geometry has been optimized using full wave simulations (CST Microwave Studio™) and a bandwidth enhancement has been achieved compared to a double layer antenna. The antenna design is based on relating the antenna performance to the reflection characteristics of the periodic array. The antenna is operating at 14 GHz with a gain of around 20 dBi and a 3dB bandwidth of around 15%.
