A Sub-6GHz 5G Switched-Beam Smart Base Station Antenna Using Dual Parabolic Cylindrical Reflectors with Multiple Feeds

摘要

A foldable/deployable 5G-sub-6GHz (3.3-7.0 GHz) switched-beam base station antenna has been developed. It consists of dual parabolic cylindrical reflectors with multiple resonant feeds. It can generate an arbitrary number of beams with arbitrary vertical/horizontal beamwidths, arbitrary beam overlapping and arbitrary electric beam-tilt for each beam. It can have a simultaneous vertical and horizontal sectorization. The peaks of the upper beams can be adjusted to be above the nulls of the lower beams and vice versa. Hence, every user will always be close to the peak of a beam. The antenna is gridded, which significantly reduces its weight and the wind-load.
