Title:
LOW-FREQUENCY RADIATION UNIT AND BASE STATION ANTENNA
Document Type and Number:
WIPO Patent Application WO/2022/012023
Kind Code:
A1
Abstract:
The present invention provides a low-frequency radiation unit, comprising a dielectric substrate, a radiator and a feeding balun, the radiator containing two orthogonally distributed dipoles, radiation arms of the two dipoles being respectively formed by a vertical line and a horizontal line and forming a cross-shaped line together, tail ends of the vertical line and the horizontal line being connected by means of a circular arc line, and a plurality of bent lines being provided in the middle of the circular arc line; and the feeding balun being of an orthogonal structure, the bottom of the feeding balun being connected to a feeding network, and the top of the feeding balun being connected to the radiator. The present invention also provides a base station antenna, which is formed by a plurality of low-frequency radiation units nested into the middle of a plurality of high-frequency radiation units. Thus, the low-frequency radiation unit of the present invention has a filtering function, can effectively reduce the effect of the low-frequency radiation unit on the high-frequency radiation performance when a high-frequency antenna and a low-frequency antenna are nested in an array, and can implement miniaturization of the antenna.
