27-28.5 GHz Ka BAND PHASED ARRAY FAN BEAM ANTENNAS AND METHODS

摘要

The disclosed 20 dBi KSF300. A high gain 5th generation mobile network or wireless system (5G) technology fan beam antenna array offers a wide 3 dB beamwidth for wide angular coverage in azimuth with most of the energy focused within 44° of the main beam. Since propagation losses at Ka band are 20× more than at 6 GHz, the beamwidth of the antenna is reduced when the antenna gain increases. To alleviate this problem, the fan-beam type antenna can be useful to provide simultaneously high gain and wide azimuth coverage.
