An improved cavity model called the modified Wolff model (MWM) is presented to compute the resonance frequency, input impedance and bandwidth of the circular microstrip antenna on thick substrate (substrate thickness, 0.003λ,g-0.1λ,g). The results of MWM show better agreement with the experimental results as compared to the results of three commercial software, including the method of moment (MOM) based Ensemble. The MWM provides deviation in resonance frequency within 1.69 % and deviation in resonant resistance within 17% against the experimental results. Copyright SBMO.
