Abstract
A parabolic rectangular horn antenna includes a source aperture, a parabolic reflector, and an output aperture. The source aperture has a first port for receiving a planar wavefront signal and a second port for providing a substantially cylindrical wavefront signal. The parabolic reflector is positioned within the horn to receive the cylindrical wavefront signal, transforming it to a substantially planar wavefront signal at a predefined location. The output aperture is positioned at the predefined location and outputs the substantially planar wavefront signal. Corrugations are adjacently placed at both sides of the output aperture to optimize the antenna beam pattern.
