A Cavity Antenna and the Device for Its Excitation

摘要

Numerical and experimental results for a planar antenna in the form of a low multimode cavity with a system of radiating holes excited by a strip line through a coupling hole are obtained. The system of integral equations with respect to the equivalent distributions of magnetic and electric currents is derived by the method of partial domains. The initial system of equations is solved by the method of moments. The results of numerical modeling are utilized in the design of antennas for direct reception of satellite television.
