Integrated Waveguide Cavity Antenna And Reflector Dish

摘要

A feed assembly for a parabolic dish reflector is described. The feed assembly includes a waveguide cavity locatable at the focal point, or any other desired off-boresight location corresponding point, of the parabolic dish, at least one first radiating element optimized for operation at a first frequency band and provided on a top surface of the waveguide cavity, and a plurality of second radiating elements each optimized for operation at a second band of frequencies and provided on the top surface of the waveguide cavity.
