CAD model to compute input impedance and bandwidth of tunable right angle isosceles triangular patch antenna

Abstract

a fast and accurate CAD model based on cavity model analysis has been proposed to predict the input impedance and bandwidth of a tunable right angle isosceles triangular patch antenna (RAITPA).The effect of suspended substrate on the input impedance and bandwidth has been thoroughly investigated. The accuracy of the present model is computed against the HFSS simulated results. The present model shows very good agreement with the simulated results. For designing the MIC on semiconductor materials with ε r ≥ 10, this model will be widely applicable.
