LINEAR ANTENNA ARRAY WITH AZIMUTH BEAM AUGMENTATION BY AXIAL ROTATION

摘要

An antenna array (100) with azimuth beam width that can be continuously augmented through on-axis rotation of a single-column or a dual-column linear array is disclosed. Alternate radiating elements (112, 122) in the vertical direction are arranged on separate reflectors (110, 120) which are movable to change their angle in the azimuth to alter beam width.
