Abstract
An electrically tilted antenna system with polarization diversity has a dual polarized, tilt adjustable antenna (). The antenna () has dipoles () of two orthogonal polarizations associated with independently adjustable electrical tilt angles. The tilt angles are implemented by relative delays between corporate feed input or output signals, the delays being introduced by an antenna tilt assembly (). Two signal feeders (F, F) associated with different antenna polarizations connect the antenna tilt assembly () to a base station filter assembly (): the base station filter assemblyroutes transmit signals from base stations (BS, BS) to different antenna polarizations via respective feeders (F, F) and the antenna tilt assembly (). This assembly also divides receive signals from feeders (F, F) between both base stations (BS, BS). Each antenna polarization is associated with transmit and receive signals of a respective base station (BSor BS) and with a polarization diversity signal of the other base station (BSor BS). The antenna system may be used with two or more base stations operating with contiguous frequencies.
