Design of a W-Band Multi-Beam Antenna Fed by Sixteen Feed-Horns Array
A W-band multi-beam Cassegrain antenna fed by a sixteen feed-horns array is designed and manufactured. The sixteen horns are arranged as a 4×4 focal plane array and they illuminate the sub-reflector and main reflector of the Cassegrain antenna to form the sixteen radiation beams. Each beam overlaps with the adjacent beam at half-power beam width (HPBW). Thus, the field of view of the multi-beam antenna achieves about 4°×4°. At the center frequency, the gains of all the beams are greater than 39.3dBi and the corresponding main beam efficiencies are larger than 45%. The gain difference among the sixteen beams is less than 1dB. The measured results agree well with the simulated results.
