Abstract :
An expedient method is presented to calculate the lumped element values of the equivalent parallel resonator circuit for a rectangular microstrip patch antenna. The model is shown to accurately predict the resonant behavior of patch antennas lacking traditional feed circuits, such as parasitic patch antennas and reflectarray unit cells. The cavity model of the rectangular patch provides the basis for analysis of the effect of tunable reactive loading on the fundamental mode resonant frequency. Predictions from the model are compared to full-wave simulation and show excellent agreement.
