Abstract: Base station antennas include a first array that has a plurality of columns of radiating elements. All of the columns in the first array except for a first column and a second column are spaced apart from adjacent of the columns of the first array by a first distance. The first and second columns of the first array are spaced apart from each other a second, larger distance (e.g., twice the first distance) to define a first column-shaped open space within the first array. A column of a second array may be positioned in the first column-shaped open space within the first array.

Abstract: Base station antennas are provided herein. A base station antenna includes a plurality of vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the vertical columns of low-band radiating elements in a vertical direction.

Abstract: Base station antennas are provided herein. A base station antenna includes consecutive first, second, third, and fourth columns of radiating elements that are configured to transmit in a first frequency band. In some embodiments, the first and third columns are further configured to transmit in a second frequency band that is different from the first frequency band as a first MIMO pair, and the second and fourth columns are further configured to transmit in the second frequency band as a second MIMO pair. Additionally or alternatively, in some embodiments, the first and second columns are fed together and are further configured to transmit in a second frequency band as a first MIMO pair, and the third and fourth columns are fed together and are further configured to transmit in the second frequency band as a second MIMO pair. Related methods of operation are also provided.

Abstract: Base station antennas include a plurality of multiplexer filters and a multi-column array of radiating elements that includes a plurality of sub-arrays. Each filter may have a first and second ports that are configured to pass RF signals in respective first and second frequency bands and a third common port that is coupled to a respective one of a plurality of sub-arrays. These antennas also include first frequency band ports that are coupled to the first ports of respective subsets of the multiplexer filters and second frequency band ports that are coupled to the second ports of at least some of the multiplexer filters. The antenna may operate as a MIMO sector antenna in the first frequency band and as a sector-splitting antenna in the second frequency band.

Abstract: Systems and methods for a diplexed antenna with semi-independent tilt are disclosed. The diplexed 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.
