THE BASE STATION ANTENNA RADIATION SYSTEM HAS A SIMPLIFIED STRUCTURE.

Abstract

The invention relates to a base station antenna radiation array with a simplified cable configuration. The proposed antenna radiation array comprises: a reflector, a perforation formed in the reflector; a feed cable running through the perforation; a feed PCB positioned away from the reflector and arranged parallel to the reflector and having a feed pattern supplied by the feed cable; multiple dipole arms positioned above or below the feed PCB to receive the feed signal from the feed pattern of the feed PCB; and a support for the feed PCB or multiple dipole arms such that the feed PCB and multiple dipole arms are positioned away from the reflector and arranged parallel to the reflector. The proposed antenna radiation array has the advantage of a simplified cable configuration through direct feeding from the feed cable without the use of a balun, and can ensure good isolation between the low-band-radiator and the high-band-radiator.
