Abstract : A mirror antenna employing a continuous mirror without a hole. A feed horn and an electromagnetic lens, located behind a rotatable twist reflector(the mirror), collimates a beam toward a polarized reflector located near the twist reflector and tilted to aim energy toward the twist reflector. Energy reflected back toward the polarized reflector from the twist reflector passes through the polarized reflector to free space. (Author)
