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
Will be all without using cable connection, therefore, use highly integrated metal band-shaped line (or printed circuit board (PCB) provided with microstrip line)
The antenna of the existing each element of use cable connection of antenna ratio of feeding network design has small insertion loss, higher gain.
This design enables us to develop the antenna with best gain.
3) as a highly integrated metal band-shaped line (or printed circuit board (PCB) provided with microstrip line) made in one piece
Feeding network, when applying to antenna for base station, it is thus only necessary to weld its company for leading defeated feeder line and input port, oscillator and feeding network
Port is connect, therefore, using the antenna of this technology, its number of welds is by the solder joint number of far smaller than rival's antenna, in production
When reduce the probability of intermodulation generation, intermodulation first-pass yield when improving 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-
Penetrate plate and phaser cavity is integrally formed, reflecting plate (surface of conductor housing) and the public face of phase shifter conductor cavity, two
Person is not separate, and reflecting plate and phase shifter are all separate parts in existing design, and phase shifter is supported
On reflecting plate, and the transmission mechanism of phase shifter is also above the cavity of phase shifter, and which adds the height of antenna.Originally set
The phase shifting equipment and strip line of meter are all directly installed in conductor cavity, and transmission mechanism is imbedded in reflecting plate (conductor housing
Surface) with phaser cavity, so can be very good to reduce the overall thickness of antenna, this design will make our antenna
Antenna thickness than any rival is all thin, and the size and volume of so whole antenna will diminish, and windage will reduce, operator
Cost of building a station accordingly reduce.
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) 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.Phase shifter structure is simple, and installation and maintenance easily, can show
Write and improve production efficiency.
9) lower floor's feeding network of the present invention includes a first input port and six the first output ports；Upper strata transmission network
Network includes six four port networks, and each four port network includes three the second output ports and logical with first output port
Cross second input port of transmission line connection.The transmission line number for connecting levels feeding network is six, levels feedback
Whole network will form one one point 18 of network, i.e., one input and 18 output ports after electric network is connected.
Because transmission line only has six, correspondingly, the number of windows for accommodating transmission line is processed on cavity and also there was only six, so
CNC processing capacities can be reduced, processing cost is reduced.
10) due to top layer strip line employ one point of three scheme (i.e. four port networks be divided into three the second output ports and
Second input port being connected with first output port by transmission line), parts count is accordingly reduced, bottom banding
The length of line will be reduced accordingly.The antenna for base station of feeding network design for example based on an input and 18 output ports
With 18 radiant bodies, its top layer strip line only has six four independent port networks and lower floor's feeding network, bottom
Banding line length will reduce, and so advantageously reduce difficulty of processing, reduce the manufacturing cost of strip line.
11) one point of three scheme is advantageously reduced the leakage of electromagnetic wave, reduced due to the number reduction of transmission line during work
Coupling, improves S parameter, improves performance；Pad will be reduced accordingly, and the destabilizing factor of welding is also reduced accordingly,
Maintenance cost is reduced, antenna length is about 1.9 meters, highest-gain reaches 21.5dBi.
