The Effect of Radome on Resonance Characteristics of Triangular Patch Antenna

Free registration required

Executive Summary

A simple and accurate CAD model based on cavity model analysis is proposed to predict the effect of superstrate or radome on resonant frequencies of an equilateral triangular patch antenna. The computed values for wide range of superstrate parameters and patch sizes are compared with different theoretical and experimental values available in open literature showing close agreement. A Maxwell's equation solver is used to generate some simulated data. Recent advanced studies on microstrip antenna with triangular patch geometry reveal the versatility of the same for miniaturization of the physical dimensions with respect to other common shapes like circular or rectangular geometry and thereby reducing the volume and weight of the antenna configuration.
