BASE STATION ANTENNA, AND RADIATING ELEMENT THEREOF

WIPO Patent Application WO/2021/063123

A1

The present application provides a base station antenna and a radiating element thereof. The radiating element comprises a dipole, a balun supporting the dipole, and a feed component feeding power to the dipole. The balun comprises a pair of balun arms disposed opposite each other, and at least one of the balun arms is configured to be hollow. The feed component comprises a feed conductor and an insulating dielectric. The feed conductor passes through the hollow balun arm and is connected to a radiating arm supported by the other balun arm. The insulating dielectric is fillingly disposed between the feed conductor and an inner wall of the balun arm, and securely fixes the feed conductor within the balun arm. The invention arranges the feed component composed by the feed conductor and the insulating dielectric in an internal cavity of the hollow balun arm, and the feed component and the balun arm compose a structure similar to that of a coaxial cable, thereby eliminating the need for a power feeding coaxial cable or a welding operation, saving on time needed for welding and alleviating electrical performance instability caused by welding. In addition, the invention does not use a coaxial cable, thereby reducing costs.
