Abstract
A multi-beam reflector antenna at W band is designed. The antenna consists of a 6×6 horn array feed, a parabolic main reflector, and a hyperbolical sub-reflector. The 3dB beam width coverage is about 7.2°×7.2°. The gain at the center frequency is greater than 35.4dBi, and the gain difference between different beams is less than 2dB. The bandwidths of all the beams are larger than 2GHz at W band. The measured results agree well with the design.
