A Sub-6 GHz Multi-Beam Base Station Antenna for 5G with an Arbitrary Beam-Tilting for Each Beam

摘要

A sub-6 GHz (3.3 - 7.0 GHz) multi-beam base station antenna has been developed for 5G. It consists of two parabolic cylindrical reflectors and several feeds. It can generate an arbitrary number of beams with arbitrary vertical and horizontal beamwidths. Each beam can be electrically tilted with an arbitrary vertical/horizontal tilt angles. It can have horizontal and vertical sectorization at the same time. This doubles the number of beams. Hence, every user will always be close to the peak of one of the beams. So, it can be used as a good configuration for switched beam smart base station antennas.
