Abstract
A planar offset-feeding Cassegrain H-plane horn antenna based on substrate integrated waveguide is proposed in this paper. Blockage effect can be avoided because the sub-reflector and feed are located out of the aperture of the main reflector. Almost uniform phase distribution can be realized by proper design of the two reflectors and the location of feeding horn. A narrow beamwidth in H plane and wide beamwidth in E plane can be achieved, and the radiation pattern is stable in the operating band from 27.5 GHz to 32.1 GHz.
