Using Green's function method for leaky-wave antenna analysis based on partially-filled slitted rectangular waveguide

Abstract

A leaky-wave antenna based on a rectangular waveguide with partially dielectric filling and long slit on the narrow wall is investigated. The Green's function method for dispersion equations and antenna radiation analysis is suggested. A protective dielectric cover on the screen with slit is taken into account. A complex propagation constant is defined by matching of magnetic fields in the slit.
