Improved CAD formulae to calculate the input impedance of an equilateral triangular microstrip patch including radome effect

Abstract

A very simple CAD formulae based on cavity model analysis is used to compute the input impedance of an Equilateral Triangular Microstrip Patch Antenna (ETMPA) for wide range of variations of superstrate parameters .The computed values are compared with theoretical and experimental values available in open literature. A simulation software (CFDTD) is also used to validate our model.
