Patent number: 11387545Abstract: The present invention relates to a radiator support for a base station antenna. The radiator support includes a first support part and a second support part that are separate from each other. The first support part is configured to be mounted to extend upwardly from a reflector plate, to extend in part of a height of the feeding stalk, and to bear radially the feeding stalk so as to prevent roll-over of the feeding stalk. The second support part is configured to be mounted adjacent a distal end of the feeding stalk facing away from the reflector plate, and to receive a radiating element. The present invention also relates to a radiator having such radiator support, and a base station antenna having such a radiator. The radiator support according to the present invention has a simple structure, occupies a small structural space and has a favorable versatility.Type: GrantFiled: October 28, 2020Date of Patent: July 12, 2022Assignee: CommScope Technologies LLCInventors: Bin Ai, Keyun Di, PuLiang Tang
