Radiating element and base station antenna

Abstract

The present disclosure relates to a radiating element, and the radiating element includes: a radiator with a radiating arm, the radiator configured to emit first electromagnetic radiation within a predetermined first operating frequency band; and a parasitic metal pattern, where a resonant circuit is formed between the radiating arm of the radiator and the parasitic metal pattern, and the resonant circuit is configured to allow an operating current on the radiating arm within the first operating frequency band to pass, but prevent an inductive current induced on the radiating arm and within a second operating frequency band. In addition, the present disclosure also relates to a base station antenna having the radiating element (FIG. 4).

Dependencies are inferred from the claim text.
