LENSED BASED STATION ANTENNAS

摘要

A lensed antenna system (10) includes a first column of radiating elements (20a) having a first longitudinal axis and a first azimuth angle, and, optionally, a second column of radiating elements (20b) having a second longitudinal axis and a second azimuth angle, and a radio frequency lens (30). The radio frequency lens has a third longitudinal axis. The radio frequency lens (30) is disposed such that the longitudinal axes of the first and second columns of radiating elements (20a, 20b) are aligned with the longitudinal axis of the radio frequency lens (30), and such that the azimuth angles of the beams produced by the columns of radiating elements are directed at the radio frequency lens. The multiple beam antenna system further includes a radome (60) housing the columns of radiating elements and the radio frequency lens. There may be more or fewer than two columns of radiating elements. The lens narrows the HPBW of the antenna arrays while increasing their gain and therefore increases the system capacity.
