Title:
RADIATION UNIT, BASE STATION ANTENNA AND BASE STATION ANTENNA FEED SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/226758
Kind Code:
A1
Abstract:
The present application provides a radiation unit, a base station antenna and a base station antenna feed system. The radiation unit comprises a dielectric body, a feed probe and an element. A first strip line is arranged on the surface of one side of the dielectric body in the thickness direction. A second strip line is arranged on the surface of the other side of the dielectric body in the thickness direction. A metal via hole passes through the dielectric body in the thickness direction. The first strip line and the second strip line are electrically connected through the metal via hole. The feed probe is electrically connected to the first strip line and the second strip line. The element is arranged on the dielectric body, and is connected to the feed probe and the metal via hole through the second strip line. When the base station antenna works in a harsh environment, even if the connection between one of the strip lines and the feed probe fails, the two strip lines can still be electrically connected through the metal via holes and are thus electrically connected to the feed probe, thereby ensuring that circuit conduction remains effective, ensuring that the base station antenna operates normally, and significantly reducing the probability of base station antenna failures.
