Zusammenfassung:Stepped radio frequency (RF) reflector antennas are disclosed in which an inner RF reflector is disposed in a central opening of at one or more annular RF reflectors. The RF reflecting surface of the inner RF reflector and the RF reflecting surface(s) of the one or more annular RF reflectors can be shaped and positioned relative to each other to have different focal lengths but nevertheless reflect an RF signal to the same focal plane. The depth of the inventive reflector antenna system can be less than the depth of prior art reflector antennas with a comparable RF aperture.
