Lensed Base Station Antennas

摘要

A lensed antenna system is provided. The lensed antenna system includes a first column of radiating elements having a first longitudinal axis and a first azimuth angle, and, optionally, a second column of radiating elements having a second longitudinal axis and a second azimuth angle, and a radio frequency lens. The radio frequency lens has a third longitudinal axis. The radio frequency lens is disposed such that the longitudinal axes of the first and second columns of radiating elements are aligned with the longitudinal axis of the radio frequency lens, 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 housing the columns of radiating elements and the radio frequency lens. There may be more or fewer than two columns of radiating elements.

1. A multiple beam antenna system comprising:
a first column of radiating elements having a first longitudinal axis and a first azimuth angle; a second column of radiating elements having a second longitudinal axis and a second azimuth angle; a radio frequency lens having a third longitudinal axis, the radio frequency lens disposed such that the first longitudinal axis and the second longitudinal axis are substantially aligned with the third longitudinal axis and the first azimuth angle and the second azimuth angle are directed at the radio frequency lens; and a radome housing the first column of radiating elements, the second column of radiating elements and the radio frequency lens.
