The present invention compares prior art, has the beneficial effect that：
1) feeding network component is put into every layer of conductor cavity by the present invention, and adjacent two layers conductor is connected at transmission line
Feeding network component in cavity, forms space multistory feeding network, and script is in the feeding network point of same layer by this design
Into two parts, it is positioned in the conductor cavity that multiple identicals are overlapped mutually, reduces the width of whole phase shifter.Work as conductor
When cavity is two layers, the width of whole phase shifter reduces nearly 50%, and the thickness increase of phase shifter only 7mm, by the sky
Between three-dimensional phase shifter when being used for antenna for base station, because we have double space, enable us to have spatially integrate feeding network
In cable, replace cable using strip line etc., design the highly integrated Wave-packet shaping network of no cable, this height collection
Into Wave-packet shaping network, by the antenna for making us possess minimum solder joint, that is, improve antenna production efficiency with it is consistent
Property, reduce the volume nearly 50% of antenna again, save material, reduce cost, be also convenient for transport and flexibly arrange net to use.
2) insertion loss of metal band-shaped line is less than the insertion loss of cable, made in one piece highly integrated as one
Metal band-shaped line feeding network when being used in antenna for base station design, the oscillator and phase shifter of antenna, between phase shifter inner member
Therefore, it will be used all without using cable connection using the antenna ratio of highly integrated metal band-shaped line feeding network design is existing
The antenna of each element of cable connection has small insertion loss, higher gain.This design enables us to develop with most
The antenna of good gain.
3) as a highly integrated metal band-shaped line feeding network made in one piece, when applying to antenna for base station, only
The connectivity port of its defeated feeder line of master of welding and input port, oscillator and feeding network is only needed, therefore, the day of this technology is used
The solder joint number of far smaller than rival's antenna is reduced the probability of intermodulation generation in production, improved by line, its number of welds
Intermodulation first-pass yield during antenna production, and the uniformity of standing wave is also fine.
4) when space multistory phase shifter is used for antenna for base station, because part realizes modularization, the assembling of this antenna
To be very simple, compared to antenna of the prior art, it is necessary to which less assembling workman, due to not needing cable, compares
In prior art, it is not necessary to cut the cable of many kinds of different lengths, it is not necessary to ensure every cable length it is accurate, need not be
Supervised during production workman whether by cable welding in correct position, reduce the quality that QC personnel examine welding.
5) in large-scale production, feeding network can be manufactured by metal stamping process, improve production efficiency, and then
Thoroughly reduce production cost.
6) traditional array antenna Adjustable Phase Shift device is to support independent conductor chamber by support column at the back side of reflecting plate
Body, installs phase shifting equipment in the conductor cavity, also, traditional each interelement of array antenna is by cable connection.U-shaped is anti-
Penetrating plate and phase shifter conductor cavity can be integrally formed, and reflecting plate (surface of conductor housing) shares one with phase shifter conductor cavity
Individual cavity wall.And reflecting plate and phase shifter are all separate parts in existing design, phase shifter is supported on reflecting plate
On, and the transmission mechanism of phase shifter is also above the cavity of phase shifter, which adds the height of antenna.The phase shift of the design
Device and strip line are all directly installed in conductor cavity, and transmission mechanism is imbedded in reflecting plate and phaser cavity, this
Sample can be very good to reduce the overall thickness of antenna, and this design will make the antenna thickness of our antenna ratio rival all
Thin, the size and volume of so whole antenna will diminish, and windage will reduce, and the cost of building a station of operator is accordingly reduced.
7) new design enables us to the demand according to client, designs the antenna of different vertical face directional diagram, and only
Only only need to change the structure of metallic conductor strip line.For example, first layer feeding network provides best gain, second layer feed
The low Sidelobe Suppression of network offer and null-fill.
8) when this space multistory phase shifter is used for antenna for base station, one feature is, if an array antenna has N number of spoke
Beam, then this feeding network will have N-1 sub- phase shifters.If for example, an antenna for base station with 12 oscillators, have
Will be comprising 11 sub- phase shifters in best directional diagram and gain, its feeding network, and rival is typically only comprising 1-5 son
Phase shifter.
9) because the feeding network of electrical tilt antenna is extremely complex, the Antenna Design of present antenna for base station enterprise has been used largely
Coaxial cable, make the pad of antenna excessive, connect up extremely complex, therefore, the production process of antenna for base station needs substantial amounts of
Workman, realizes that automation is extremely difficult.Because the design has Highgrade integration feature, therefore, designed using this technology
Product can fully achieve automated production in its production process, all welding and assembling will be come in fact by robot completely
It is existing, this have the consequence that, the production efficiency of antenna will be 5-8 times of traditional antenna enterprise, due to Highgrade integration feature, give birth to
The antenna uniformity that output is come will be increased substantially, and reduce fraction defective.Phaser mechanism is simple in construction, and installation and maintenance are easy, energy
Significantly improve production efficiency.
