Abstract: Base station antennas are provided herein. A base station antenna includes first and second wiper phase shifters. In some embodiments, the base station antenna includes first and second wiper supports that are on the first and second wiper phase shifters, respectively, and the first wiper support includes a portion that is beside and interlocked with a portion of the second wiper support. In some embodiments, the base station antenna includes a first linkage that is on the second wiper phase shifter, and a second linkage that intersects, and is coupled to, the first linkage and is configured to adjust the first and second wiper phase shifters via the first linkage. In some embodiments, the first and second wiper phase shifters are a mirror-image pair of wiper phase shifters. Related methods of operating a base station antenna are also provided.

Abstract: A tilt adapter configured to facilitate a desired tilt of a first radio frequency (RF) band and a second RF band of an antenna is disclosed. The antenna supports two or more frequency bands, in which the vertical tilt of each of the supported frequency bands is separately controlled by a coarse level of phase shifting, but commonly controlled by a fine level of phase shifting.
