Abstract :
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.
