Abstract

The performance of microstrip patch antenna system depends on the characteristics of the antenna element and the substrate as well as the feed configuration employed. Here the principal characteristics of interest are the antenna input impedance, mutual coupling, bandwidth, radiation pattern and return loss. In large multilayer array networks the computational time and effort required for the analysis of these characteristics become important with size and complexity of the geometries of the antenna systems. In this paper, we combine the simplicity of the Transmission Line method and the accuracy of the Integral Equation method to obtain a Hybrid method. First we develop a simplified equivalent circuit model of a single aperture-coupled patch antenna using the Transmission Line method. Then we develop a simplified model that can be used to efficiently analyse the characteristics of an aperture-coupled patch antenna array, using the Integral Equation Method. For its application to the problems of antenna phased arrays, a modification of the model will be obtained, taking into account the effects of coupling between the antenna elements and the resulting reflection coefficient which is related to scan blindness and surface waves. The major advantage of the proposed model is the reduction of the large computing time involved in the existing rigorous method which is based on the combined field Integral Equations and the Method of Moments (MoM).
