Input admittance of circular waveguide opening mounted on dielectric-covered grounded spherical surface

The paper deals with a circular waveguide antenna mounted on a grounded spherical surface with a dielectric coating. The analysis method is based on the moment method in the spectral domain. The influence of thickness and permittivity of dielectric radome is discussed. The analysis method is verifie...

Description
Summary:The paper deals with a circular waveguide antenna mounted on a grounded spherical surface with a dielectric coating. The analysis method is based on the moment method in the spectral domain. The influence of thickness and permittivity of dielectric radome is discussed. The analysis method is verified by comparing the theoretical results with measurements.
