This study presents theoretical formulation and results for cavity‐backed annular conical antennas. The formulation is based on equivalence principle and method of moments (MoM), in both point‐matching and Galerkin forms. Results are presented for radiation diagram, and input impedance, and compared to those obtained using commercial software. The effects of dielectric thickness and of cavity dimensions on input impedance are presented. In addition, the feeding using two coaxial cables for radiation maximum at cone axis is also presented.
