Abstract

The invention discloses a dual-polarized broadband radiating element used on a TD-LTE intelligent antenna. The dual-polarized broadband radiating element comprises a radiating oscillator, a directing piece, a directing piece support frame and a reflecting plate, wherein the radiating oscillator is formed by two polarized symmetrical dipoles which are crossed orthogonally, and is fixed on the reflecting plate; the directing piece is fixed on the directing piece support frame; the directing piece support frame is fixed on the oscillator arms of the radiation oscillator. The dual-polarized broadband radiating element has the advantages as follows: the standing waves are good; the working frequency band is wide; the gain is high; the production is convenient; the mounting is easy; the consistency is high. Therefore, the dual-polarized broadband radiating element better meets the high-performance requirements of the TD-LTE intelligent antenna.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dual-polarized broadband radiation unit for a TD-LTE smart antenna. Background technique [0002] The transmission and coverage of signals in mobile communication technology are inseparable from base station antennas. Dual-polarization base station antennas are an indispensable part of every communication base station, and its performance directly affects the quality of communication. The radiation unit of the antenna is the most basic and important part of a dual-polarized base station antenna. [0003] With the rapid development of 4G communication technology, the demand for TD-LTE smart antenna is more urgent. The gain of the traditional cross dipole is limited, and it is impossible to design a high-gain array antenna; and the traditional cross dipole VSWB and pattern bandwidth are narrow, which cannot meet the broadband radiation requirements of TD-LTE. The traditio...
