Abstract
The utility model discloses a dual-polarized TD-SCDMA intelligent antenna radiation oscillator, which is characterized by comprising a radiation body, a feed sheet and a positioning medium. The radiation body has an integral structure formed by combining two sets of symmetric dipoles into a whole and adopting one-step pressing molding, the bottom portion of the radiation body is provided with a threaded hole for fixing, the lower portion of the radiation body is provided with a boss for positioning, and the top portion of the radiation body is provided with a radiation arm. The feed sheet is fixed on the radiation body through the positioning medium. The dual-polarized TD-SCDMA intelligent antenna radiation oscillator has the advantages of accurate size, simple structure, convenient installation, improved working efficiency and low cost.
Description
Technical field
The utility model relates to a kind of microwave communication antenna radiation unit, specifically a kind of double polarization T D-SCDMA smart antenna radiating doublet that utilizes the global design of symmetrical dipole principle.
Background technology
Antenna is the mobile communication system important component part, and antenna is made up of one or more radiating elements, thereby the performance of radiating element has determined the antenna overall performance.
Existing radiating element is formed a dual-polarization radiating unit by two groups of symmetrical dipoles, and each radiating element is installed dual-polarization radiating unit of recomposition respectively.This structure has caused the reduction of production efficiency; Simultaneously owing to be artificial installation, the variation that brings electric property easily; And radiating element quantity is also many, and the cost of antenna increases accordingly.
Summary of the invention
The purpose of this utility model provides a simple in structure, easy for installation, double polarization T D-SCDMA smart antenna radiating doublet that price is low.
The purpose of this utility model is achieved through the following technical solutions:
A kind of double polarization T D-SCDMA smart antenna radiating doublet, it is characterized in that: this radiating doublet comprises radiant body, feed tab and location medium, described radiant body is for being integrated two groups of symmetrical dipoles and adopting the one-time formed overall structure of pressure injection, be provided with the screwed hole that is used for fixing in the radiant body bottom, the radiant body bottom is provided with the boss that is used to locate, and is provided with radiation arm at the radiant body top; Feed tab is fixed on the radiant body by the location medium.
In the utility model, feed tab is by locating medium welding on radiant body.
The utility model radiant body adopts global design, two groups of symmetrical dipoles is designed to one adopts the pressure injection one-shot forming, is convenient to the accurate of design size like this.The radiant body bottom has a screwed hole to be used for fixing, and simultaneously the radiant body bottom is designed to boss structure and is used for the location.Feed tab is fixed on the radiant body by the location medium, links to each other with radiant body by welding again.
Compared with prior art, the utility model adopts injection-compression molding, and size can guarantee accurately; And because two groups of dipoles are designed to one, simple in structure, easy for installation, improved production efficiency, reduced cost.
