a simple and efficient CAD model based on cavity model analysis is proposed to compute accurately the resonant frequency of radome loaded rectangular patch antenna. The computed values for wide range of radome parameters are compared with different theoretical and experimental values available in open literature. Our computed values are closer to the experiments compared to the others.
Abstract-In this article, a set of closed-form expressions is proposed to predict the resonant frequency, quality factor, input impedance, bandwidth efficiency, directivity and gain for a coax-fed electromagnetically coupled stacked rectangular patch antenna. The computed results obtained with the present model are compared with the experimental and HFSS simulated results. The present model shows less error against the experimental and simulated results.
