A modified cavity model to compute the resonance frequency of a rectangular patch antenna on a thick polytetrafluoroethylene substrate (0.037λg - 0.229λg) with maximum deviation of 2% against experimental results is presented. This accuracy is achieved by accounting for the effect of anisotropy and total losses on the resonance frequency. All other models, including the method of moments (MOM)-based Ensemble, compute resonance frequency with error between 4 and 36%.
