Dual polarization wireless repeater including antenna elements with balanced and quasi-balanced feeds

摘要

Wireless repeaters that utilize balanced and quasi-balanced antenna feed circuits for feedback suppression. The wireless repeater typically implements dual cross-polarization isolation both along and between uplink and downlink signal paths, which relies on dual-polarization server and donor antennas. The unit may utilize balanced antenna feeds for both polarizations or balanced antenna feeds for one polarization and unbalanced antenna feeds for the other polarization. In addition, the unbalanced antenna feeds may be deployed in a two-element quasi-balanced configuration, and the antenna may include dual-polarization antenna element. The antenna elements may include dual-polarization antenna elements or separate antenna elements for each polarization.
