Closed-Form Formulas of Input Impedance and Axial Ratio of a Circular Patch With Perturbation Segments

We present a simple and useful closed-form expression to compute antenna input impedance and the axial ratio of a circular patch antenna with perturbation segments. The closed-form expression is obtained by applying the cavity perturbation theory on antenna equivalent circuits that represent the res...
