    Abstract: An antenna comprises an array of radiating elements including a first column located at a side portion of the antenna and a second column located at a middle portion of the antenna. A feed network for the antenna comprises a filter at least partially filtering out a signal within the first sub-band of an operating frequency band of the antenna, such that the signal strength of a first sub-component of the signal within the first sub-band for the first column is smaller than the signal strength of a second sub-component of the signal within the first sub-band for the second column, and the signal strength of a first sub-component of the signal within a second sub-band of the operating frequency band of the antenna for the first column is not smaller than the signal strength of a second sub-component of the signal within the second sub-band for the second column.

    Abstract: A twin beam base station antenna includes a first array that has a plurality of columns of first frequency band radiating elements, the first array configured to form a first antenna beam that provides coverage throughout a first sub-sector of a three-sector base station. The radiating elements in a first of the columns in the first array have a first azimuth boresight pointing direction and the radiating elements in a second of the columns in the first array have a second azimuth boresight pointing direction that is offset from the first azimuth boresight pointing direction by at least 10°. The radiating elements in the second of the columns in the first array are electrically steered.

    Abstract: The present invention provides a phase shifter assembly for an array antenna, comprising: a first level phase shifter, wherein the first level phase shifter is configured to control the phases of a plurality of sub-arrays of the array antenna, where each sub-array comprises one or more radiating elements; a second level phase shifter, wherein the second level phase shifter is configured to proportionally change the phases of the radiating elements in the corresponding sub-arrays; and a power divider, wherein the power divider is connected between the first level phase shifter and the second level phase shifter. The phase shifter assembly has the advantages of both a distributed phase shifter network and a lumped phase shifter network. Specifically, the phase shifter assemblies can independently control the phases of the radiating elements in the array to obtain better sidelobe suppression. Further, phase control parts of the phase shifter are concentrated within a certain physical space range, so the size of the phase shifter assembly may be greatly decreased, and the cost may be greatly reduced, as compared with a conventional distributed phase shifter assembly design.
