摘要： The present invention relates to an antenna assembly for a beamforming antenna, comprising a reflector and an antenna array that includes a plurality of first radiating elements that are arranged as a first vertically extending array, the first radiating elements extending forwardly from the reflector; and a plurality of second radiating elements that are arranged as a second vertically extending array, the second radiating elements extending forwardly from the reflector. Two adjacent first radiating elements are spaced apart from one another by a first distance, and a first radiating element and an adjacent second radiating element are spaced apart from one another by a second distance. The first distance is substantially equal to the second distance. The antenna assembly further comprises a plurality of parasitic elements that are placed along sides of the first and second of the vertically extending arrays.

摘要： A radiating element comprises a radiator, a feed stalk and a parasitic element. The radiator is fed by the feed stalk, and the parasitic element includes an electrically conductive structure that includes a meandered electrically conductive path. A coupling capacitor is formed between the electrically conductive structure and the radiator, and a center frequency of an operating frequency band of the radiator is higher than a center frequency of a first operating frequency band of the parasitic element.

摘要： 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.

摘要： A reflector for a base station antenna comprises: a body; and at least one slot provided in the body, where the at least one slot is configured for forming at least one stub-type filtering structure in the body. The stub-type filtering structure is configured for at least partially inhibiting an induced current in the body within an operating frequency band of a radiating element mounted behind the reflector.

摘要： The present invention relates to a base station antenna, comprising: a plurality of first radiating elements that are arranged as a first vertically-extending array; a plurality of second radiating elements that are arranged as a second vertically-extending array, where the second radiating elements are staggered in the vertical direction with respect to the first radiating elements; wherein phase centers in an azimuth plane for first sub-arrays of the first radiating elements are substantially the same as phase centers in the azimuth plane for respective third sub-arrays of the second radiating elements, and wherein the first sub-arrays each have a first number of first radiating elements and the third sub-arrays each have a second number of second radiating elements, the first number being different than the second number. This can effectively improve the pattern of the base station antenna.
