Title:
LOW-FREQUENCY RADIATION UNIT AND BASE STATION ANTENNA
Document Type and Number:
WIPO Patent Application WO/2022/021824
Kind Code:
A1
Abstract:
The present invention provides a low-frequency radiation unit, comprising a radiator, a feed balun and a bottom plate. The radiator comprises two pairs of orthogonally distributed annular radiation arms, each annular radiation arm is divided into a plurality of wide line segments, and every two adjacent wide line segments are connected by means of a bent line; and the feed balun is of an orthogonal structure, the top of the feed balun is connected to the radiator, and the bottom of the feed balun is connected to the bottom plate. The present invention further provides a base station antenna comprising the low-frequency radiation unit. Therefore, the low-frequency radiation unit of the present invention has a space decoupling function, the influence of a low-frequency radiation unit on the high-frequency radiation performance can be effectively reduced when a high-frequency antenna and a low-frequency antenna are nested and arrayed, and the miniaturization of an antenna size can be achieved.
