Radiator, radiation assembly and antenna

Abstract

Embodiments of the present disclosure provide a radiator and a radiation assembly for an antenna and an associated antenna. The radiator comprises a conductive body adapted to be arranged in an antenna for transmission and/or reception of radiation in a first frequency band, wherein along a length direction of the conductive body, the conductive body comprises: a plurality of first conductive members; and at least one second conductive member galvanically coupled to the plurality of first conductive members and having a size smaller than a size of each of the first conductive member to thereby converge induced current electrometrically coupled onto the radiator by radiation in a second frequency band different from the first frequency band. With the radiation assembly comprising the radiator, other antennas or radiation assemblies operating at different frequency bands may be located closer to the radiation assembly because less electromagnetic coupling occurs between the two antennas/radiation assemblies. Accordingly, more radiation assemblies operating at different frequency bands can be arranged in the antenna, thereby increasing the radiation range of the base station without degrading the performance of the antenna and even the base station.
