Abstract

The invention provides a low-frequency radiation unit. The low-frequency radiation unit comprises a radiator, a feed balun and a bottom plate, the radiator comprises two pairs of annular radiation arms which are orthogonally distributed, each annular radiation arm is divided into a plurality of wide line segments, and every two adjacent wide line segments are connected through a bent line. The feed balun is of an orthogonal structure, the top of the feed balun is connected with the radiator, and the bottom of the feed balun is connected with the bottom plate. The invention also provides a basestation antenna comprising the low-frequency radiation unit. Therefore, the low-frequency radiation has a space decoupling function, the influence of the low-frequency radiation unit on the high-frequency radiation performance can be effectively reduced when the high-frequency antenna and the low-frequency antenna are nested to form an array, and the miniaturization of the antenna size can be realized.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a low-frequency radiation unit and a base station antenna. Background technique [0002] In recent years, wireless communication technology has developed rapidly, with full coverage from 2G and 3G to the present 4G. The 5th generation mobile communication network has also begun to be deployed, and wireless communication equipment is developing in the direction of multi-frequency, miniaturization and high performance. Antenna, as the most terminal passive component of wireless mobile communication, has always been a hotspot of wireless communication technology research, and its performance will directly affect the performance of wireless communication. In order to adapt to the rapidly developing wireless communication system, miniaturization and multi-frequency of wireless communication base station antennas have become an urgent market demand. [0003] The multi...
