ABSTRACT:
A multi-beam lens antenna for individual communication with communication satellites spaced at small elongations. The multi-beam antenna comprises primary feeds3each of which is composed of a waveguide having an opening at the end and a dielectric body6disposed at the end, a hemispherical Luneberg radio wave lens, and a reflective plate attached to the circular opening of the hemispherical radio wave lens and adapted for reflecting a radio wave incoming from the sky or emitted toward a target. The waveguides are preferably rectangular waveguides4rather than circular waveguides5. The dielectric bodies6are preferably tapered.
