Accurate model to compute of resonant frequency of right angle isosceles triangular patch antenna

Abstract

A simple and accurate CAD model based on cavity model analysis has been proposed to compute the resonance frequency of a right angle isosceles triangular patch antenna (45°-45°-90°). A standard electromagnetic simulator (HFSS) has been employed to validate the present model. The model is found to be valid for wide range of antenna parameters. Good correlation (average % error 0.94) is seen between theoretical and simulated values compared to other model available in literature.
