Multi-sector base station antenna system offering both polarization and spatial diversity

摘要

A multiple sector cell-site configuration comprises a support frame and a plurality of antennas mounted on the support frame. The antennas include one transmit antenna element and two receive antenna elements for each sector of the multiple sector cell-site. One of the receive antenna elements for each sector of each two adjacent sectors is located in a common housing mounted adjacent a given point on the support frame located substantially along a boundary between the two adjacent sectors. Each of the receive antenna elements mounted in each housing has an offset azimuthal beam directed toward its associated sector, and each of the transmit antenna elements has an azimuthal beam directed toward its associated sector.
