Problems solved by technology

[0002] At present, there are various types of antennas, which are widely used in wireless communication fields such as mobile phones, automobiles, and computers. The dual-polarized antenna oscillators used in general mobile communication base station antennas are mainly composed of a base and a vibrator body fixed on the base. Composition, the base is a circular base, usually made of metal copper, the main body of the vibrator and the base are connected by welding, and the structure is firm. The disadvantage of this structure is that the accuracy cannot meet the requirements at high frequencies, and the anti-interference ability is weak. The main body of the vibrator has complex processing technology, inconvenient wiring installation, and high manufacturing cost
The other is a printed board type vibrator. The frequency band of this antenna vibrator is too narrow. Although the bandwidth can be increased by adding one or more layers of parasitic sheet technology, the bandwidth is still not enough, and the use of line installation in the array at high frequencies is not enough. Convenient, and radiation efficiency is relatively low at high frequencies

Abstract

The invention discloses an integral type bipolar antenna element, which comprises an element main body and positioning and connecting sheets. The bipolar antenna element is characterized by comprising hollow-out double sector radiation units with four pored radiation fin bodies, wherein each unit consist of two centrosymmetrical element sheets; and the radiation fins, support posts and a fixed seat are integrated as a whole. The element can work at a frequency band from 1 to 2 GHz with voltage standing waves of less than 1.25 and can adjust horizontal beam width according to requirements. The element simplifies processing technique, greatly reduces the production cost, and has the advantages of high gain, wide transmission band, high work frequency, high interference resistance, simple structure and low manufacturing cost.
