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

Embodiment Construction

[0018] The technical solution will be described in detail below in conjunction with specific embodiments.

[0019] Such as Figure 1-Figure 5 As shown, the present invention is a high-performance ultra-wideband antenna vibrator, which includes a power divider 1 and two vibrators 2 arranged on it. The vibrator includes a vibrator main body 2-1 and a feeder 2-2. The vibrator main body includes four Group radiator 2-11, balun holder 2-12, the end of the radiator is provided with a hanging arm structure 2-13, which can increase the current path, optimize S parameters and pattern parameters, and improve the bandwidth; The bottom is connected and fixed with the power dividing board, and the power dividing board is provided with a strip line 3 connected between the two vibrators. In this embodiment, the radiator 2-11 has a box structure, one end of the radiator is connected to the balun holder, and a connecting bar 2-111 is provided at the diagonal position of the box, and the connecti...

Abstract

The invention discloses a high-performance ultra-wideband antenna oscillator which is characterized by comprising a power dividing plate and two oscillators arranged on the power dividing plate, wherein each oscillator comprises an oscillator body and a feed piece; the oscillator body comprises four groups of radiation pieces and a Balun fixing seat; a plumbing arm structure is arranged at the endpart of each radiation piece; the bottom of the Balun fixing seat is fixedly connected with the power dividing plate; and a strip line connected between the two oscillators is arranged on the power dividing plate. The high-performance ultra-wideband antenna oscillator disclosed by the invention has a simple structure; and due to the feed way, back wiring is reduced, the processes are cut down, the mounting is facilitated, and the cost is lowered.

Description

Technical field [0001] The present invention relates to the technical field of communication equipment, in particular to an antenna oscillator. Background technique [0002] At present, there are various types of existing antennas, which are widely used in wireless communication fields such as mobile phones, automobiles, and computers. Generally, the dual-polarized antenna element used in mobile communication base station antennas is mainly composed of a base and a main body fixed on the base. The base is a circular base, usually made of metal copper. The main body of the vibrator and the base are connected by welding. The structure is firm. The disadvantage of this structure is that the accuracy is not up to the requirements at high frequencies and the anti-interference ability is weak. The main body of the vibrator has complex processing technology, inconvenient line installation, and high manufacturing cost. The other is a printed board-type vibrator. The frequency band of th...
