摘要：
A new model is presented for calculating the input impedance of a probe-fed circular antenna with and without air gaps between the substrate and the ground plane. It is based on the cavity model, the dynamic permittivity constant (to take into account the influence of the fringing field at the edge of radiating element), and the resonant parallel R -L -C circuit with an inductive reactance. Numerical results are compared with experimental ones. This model is well suited for computer-aided design. © 1990 IEEE
