An efficient method to design planar arrays for high power applications by mutual coupling optimization

The performances of arrays for high power applications may be heavily affected by the mutual coupling introduced among the radiators. The phenomenon is particularly annoying when high coupling-sensitive radiators are used. The paper focuses on a simple and low computational cost method aimed to compensate the undesired coupling effects which could bring the antenna performance to be different from the theoretical ones. The method is demonstrated via simulation using the commercial software CST MICROWAVE STUDIO®.
