Abstract
Official abstract text for this publication.
Base station antennas comprise a multi-column, multiband beamforming array that includes a first sub-array of first radiating elements, a second sub-array of second radiating elements and a third sub-array of third radiating elements. The first radiating elements are configured to operate in a first frequency band, the second radiating elements are configured to operate in a second frequency band, and the third radiating elements are configured to operate in both the first frequency band and the second frequency band. Each of the first through third sub-arrays has the same number of columns. A width of the first sub-array exceeds a width of the third sub-array, and a width of the third sub-array exceeds a width of the second sub-array.
First claim
Opening claim text (preview).
That which is claimed is: 1. A base station antenna, comprising: a multi-column, multiband, longitudinally-extending beamforming array comprising a first sub-array of first radiating elements, a second sub-array of second radiating elements and a third sub-array of third radiating elements, wherein the first radiating elements are configured to operate in a first frequency band, wherein the second radiating elements are configured to operate in a second frequency band that is different from the first frequency band, wherein the third radiating elements are configured to operate in both the first frequency band and the second frequency band, wherein each of the first through third sub-arrays has a same number of columns, wherein a width of the first sub-array exceeds a width of the third sub-array, and wherein the width of the third sub-array exceeds a width of the second sub-array. 2. The base station antenna of claim 1 , wherein the third sub-array is positioned between the first sub-array and the second sub-array. 3. The base station antenna of claim 1 , wherein an average spacing in a longitudinal direction between the first radiating elements in a first column of the first sub-array exceeds an average spacing in the longitudinal direction between the third radiating elements in a first column of the third sub-array. 4. The base station antenna of claim 3 , wherein the average spacing in the longitudinal direction between the third radiating elements in the first column of the third subarray exceeds an average spacing in the longitudinal direction between the second radiating elements in a first column of the second sub-array. 5. The base station antenna of claim 1 , wherein the second radiating elements have a same design as the third radiating elements but have a different design than the first radiating elements. 6. The base station antenna of claim 1 , wherein the first radiating elements have a different design than the second radiating elements and the third radiating elements, and wherein the second radiating elements have a different design than the third radiating elements. 7. The base station antenna of claim 1 , wherein the first frequency band is at lower frequencies than the second frequency band. 8. The base station antenna of claim 1 , wherein at least some of the first radiating elements are configured to receive higher power sub-components of a first frequency band RF signal than are at least some of the third radiating elements. 9. The base station antenna of claim 1 , wherein at least some of the second radiating elements are configured to receive higher power sub-components of a second frequency band RF signal than are at least some of the third radiating elements.
