Abstract

The invention relates to the field of mobile communication base station antennas, and in particular relates to an umbrella-shaped ultra-wideband bipolarization base station antenna radiation unit mounted on a reflection plate for forming an antenna. The umbrella-shaped ultra-wideband bipolarization base station antenna radiation unit comprises a plurality of support elements fixed on the reflection plate, a plurality of radiation bodies and an electricity feed cable, wherein the plurality of radiation bodies are formed through extending from the first ends of the support elements; the electricity feed cable feeds electricity for the radiation bodies; the plurality of radiation bodies form two groups of half-wave vibrators in mutual orthogonality; the corresponding connection part of the electrical connection of the electricity feed cable and the radiation bodies is lower than the upper surfaces of the radiation bodies. The difference is that each radiation body consists of a horizontal radiation body and a bent radiation body; and the tail end extending outward of each horizontal radiation body is connected with the bent radiation body bending downward. The umbrella-shaped ultra-wideband bipolarization base station antenna radiation unit provided by the invention is high in impedance band width, high in insulation degree and high in crossed polarization ratio.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to an umbrella-shaped ultra-broadband dual-polarization base station antenna radiation unit. Background technique [0002] With the rapid development of mobile communication technology, the requirements for mobile communication base station antennas are getting higher and higher. First of all, there is a large requirement for bandwidth, and the base station antenna is required to be compatible with as many communication systems as possible. The working frequency of DCS (Digital Cellular System, digital cellular system) is 1710-1880MHz, the communication frequency of PCS (Personal Communications Service, personal communication service) is 1850-1990MHz, and the communication frequency of UMTS (Universal Mobile Telecommunications System, universal mobile communication system) The frequency is 1920-2170MHz, and the working frequency band of LTE (Long Term Evolu...
