High-gain high-precision positioning antenna and its array applied to base stations

Abstract

The invention discloses a high-gain and high-precision positioning antenna applied to a base station and an array thereof. The high-gain and high-precision positioning antenna comprises an antenna radiation unit composed of a radiation vibrator, a power feeding part and a transmission line, a DGS structure reflective plate composed of a DGS structure having -90 degree-90 degree reflective phase characteristic and coaxial feeder; An antenna radiation unit that receives an excitation and emits an electromagnetic wave or receives an electromagnetic wave and converts the electromagnetic wave intoan electrical signal; DGS structure reflect plate, reflecting energy emit by antenna radiation unit, increasing gain and improving radiation characteristic; A coaxial feed line for transmitting energyto an antenna radiation unit; The antenna array of the high gain and high precision positioning antenna applied to the base station comprises at least one antenna group composed of two antennas, allantennas are closely arranged and located in the same plane, and the antenna spacing is >=0; The antenna and the antenna array of the invention have stable radiation performance, good impedance bandwidth characteristics and directivity of the working frequency band.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a high-gain and high-precision positioning antenna array applied to a base station. Background technique [0002] After rapid development in the past 30 years, wireless communication systems have been embedded in every aspect of our lives. As the data transmission center in the system, the wireless communication base station refers to the mobile communication exchange center and signal transceiver station that exchanges data with mobile terminals through radio wave transmission and reception within a certain area. As the most important radio frequency component in the base station, the communication antenna is mainly responsible for converting the digital signal transmitted from the front end of the communication equipment into space electromagnetic waves, and vice versa. With the rapid development of 2G / 3G / 4G / 5G wireless communication systems, base station antennas also nee...
