Abstract :
A dielectric lens antenna with a scanning reflector that is coaxial to the lens is described, and its aberrations are analyzed. The result shows that aberrations of the system will deteriorate severely when a planar reflector is used, but the aberrations can be significantly reduced when a corrected phase reflector is used.
