The utility model compares the prior art, has the beneficial effect that：

1) feeding network component is put into every layer of conductor cavity by the utility model, and adjacent two layers are connected at transmission line Feeding network component in conductor cavity forms space multistory feeding network, this design will be in the transmission network of same layer originally Network is divided into two parts, is positioned in multiple identical conductor cavitys being overlapped mutually, the width of entire phase shifter is made to reduce.When When conductor cavity is two layers, the width of entire phase shifter reduces nearly 50%, and the thickness increase of phase shifter only 7mm, will When the space multistory phase shifter is used for antenna for base station, since we have double space, enable us to have spatially integrate feed Cable in network replaces cable using strip line etc., designs the highly integrated Wave-packet shaping network of no cable, this height The antenna for making us, is possessed minimum solder joint by the integrated Wave-packet shaping network of degree, that is, improve the production of antenna efficiency and Consistency, and reduce the volume nearly 50% of antenna, material is saved, cost is reduced, is also convenient for transport and use of flexibly arranging net.

2) insertion loss of metal band-shaped line is less than the insertion loss of cable, and what is manufactured as a whole is highly integrated Metal band-shaped line feeding network in antenna for base station design when, the oscillator and phase shifter of antenna, between phase shifter internal element Cable connection will not all be used, therefore, uses highly integrated metal band-shaped line (or printed circuit board equipped with microstrip line) The existing antenna using each element of 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) the highly integrated metal band-shaped line (or printed circuit board equipped with microstrip line) manufactured as a whole Feeding network, when applying to antenna for base station, it is thus only necessary to weld it and lead defeated feeder line and input port, the company of oscillator and feeding network Port is connect, therefore, using the antenna of this technology, number of welds is producing the solder joint number of far smaller than rival's antenna When reduce the probability of intermodulation generation, intermodulation first-pass yield when improving antenna production, and the consistency of standing wave is also fine.

4) when space multistory phase shifter is used for antenna for base station, since component realizes modularization, the assembling of this antenna To be it is very simple, compared with the prior art in antenna, need less assembling worker to be compared due to not needing cable In the prior art, the cable of many kinds of different lengths need not be cut, be not necessary to guaranty that every cable length it is accurate, need not be When production supervise worker whether by cable welding in correct position, reduce QC personnel examine welding quality.

5) in large-scale production, feeding network can be manufactured by metal stamping process, improve production efficiency, in turn 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- It penetrates plate and phaser cavity is integrally formed, reflecting plate (conductor surface of shell) and the public face of phase shifter conductor cavity, the two It is not independent from each other, and reflecting plate and phase shifter are all independent from each other component in existing design, phase shifter is supported on 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.The design Phase shifting equipment and strip line be all directly installed in conductor cavity, transmission mechanism be imbedded in reflecting plate (conductor shell Surface) with phaser cavity, it can be very good the thickness of diminution antenna entirety in this way, this design will make our antenna ratio The antenna thickness of any rival is all thin, and the size and volume of antenna entire in this way will become smaller, and windage will reduce, operator Cost of building a station accordingly reduces.

7) new design enables us to the demand according to client, designs the antenna of different vertical face directional diagram, and only Only need the structure of change metallic conductor strip line.For example, first layer feeding network provides best gain, second layer feed Network provides low Sidelobe Suppression and null-fill.

8) since the feeding network of electrical tilt antenna is extremely complex, the Antenna Design of present antenna for base station enterprise has used largely Coaxial cable, keep the pad of antenna excessive, wiring is extremely complex, and therefore, the production process of antenna for base station needs a large amount of Worker realizes that automation is very difficult.Since the design has the characteristics that Highgrade integration, it is designed using this technology Product can fully achieve automated production in its production process, all welding and assembling will be completely by robot Lai real 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 consistency that output is come will increase substantially, and reduce fraction defective.Phase shifter structure is simple, and installation and maintenance are easy, and can be shown It writes and improves production efficiency.

9) lower layer's feeding network of the present invention includes a first input port and two the first output ports；Upper layer transmission network Network includes two seven port networks, and each seven port network includes six second output terminal mouths and leads to first output port Cross second input port of transmission line connection.The transmission line number for connecting levels feeding network is two, levels feedback Whole network will form one one point 12 of network, i.e., one input and 12 output ports after electric network is connected. Due to transmission line only there are two, correspondingly, on cavity processing for accommodate the number of windows of transmission line also only there are two, in this way CNC processing capacities can be reduced, processing cost is reduced.

10) due to top layer strip line use one point of six scheme (i.e. seven port networks be divided into six second output terminal mouths and Second input port being connect by transmission line with first output port), parts count is accordingly reduced, and bottom is band-like The length of line will be reduced accordingly.Such as the antenna for base station of the feeding network design based on an input and 12 output ports With 12 radiators, only there are two independent seven port network and lower layer's feeding networks for top layer strip line.For It at least will be more than 2.5 meters that one, which has its length of the antenna for base station of 12 radiators, if top layer strip line is one point of six side Case, compared with the existing technology, the band-like line length of bottom will reduce, and advantageously reduce difficulty of processing in this way, reduce the system of strip line Cause this；Pad will be reduced accordingly, and the destabilizing factor of welding also reduces accordingly, reduces maintenance cost.

11) compared with the existing technology, one point of six scheme is reduced due to the number of transmission line, and when work advantageously reduces electromagnetism The leakage of wave reduces coupling, improves S parameter, improves performance.
