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, reduces the width of whole phase shifter.When When conductor cavity is two layers, the width of whole 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 the solder joint of minimum by the integrated Wave-packet shaping network of degree, that is, improve the production of antenna efficiency and Uniformity, and reduce the volume nearly 50% of antenna, material is saved, reduces cost, is also convenient for transport and flexible use of arranging net.

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 built-in component Will be all without using cable connection, therefore, use highly integrated metal band-shaped line (or printed circuit board (PCB) equipped with microstrip line) The existing antenna using each element of cable connection of antenna ratio of feeding network design has small insertion loss, the gain of higher. 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) equipped with microstrip line) made in one piece Feeding network, when applying to antenna for base station, it is thus only necessary to weld it and lead the company of 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 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 uniformity 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, it is necessary to which less assembling worker, since cable is not required, compares In the 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 worker 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 that independent conductor chamber is supported by support column at the back side of reflecting plate Body, installs phase shifting equipment in the conductor cavity, also, each interelement of traditional array antenna is by cable connection.U-shaped is anti- Penetrate plate and phaser cavity is integrally formed, reflecting plate (conductor surface of shell) and the public face of phase shifter conductor cavity, both It is not mutually independent, and reflecting plate and phase shifter are all mutually independent components 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 housing Surface) with phaser cavity, so can be very good the thickness of diminution antenna entirety, this design will make our antenna ratio The antenna thickness of 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 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, make the pad of antenna excessive, wiring is extremely complex, and therefore, the production process of antenna for base station needs substantial amounts of Worker, realizes that automation is extremely difficult.Since the design has the characteristics that Highgrade integration, designed using this technology Product can fully achieve automated production in its production process, all welding and assembling will be completely by robots 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 uniformity that output is come will increase substantially, and reduce fraction defective.Phase shifter structure is simple, and installation and maintenance are easy, can show Write and improve production efficiency.

9) lower floor's feeding network of the present invention includes a first input port and three the first output ports；Upper strata is fed Network includes three five―port networks, each five―port network include four the second output ports and with first output port Second input port connected by transmission line.The transmission line number for connecting levels feeding network is three, levels Whole network will form one one point 12 of network, i.e., one input and 12 output terminals after feeding network is connected Mouthful.Since transmission line only has three, correspondingly, the number of windows that processing is used to accommodate transmission line on cavity also only has three, CNC processing capacities can be so reduced, reduce processing cost.

10) the utility model using transmission line due to being connected, and pad will be reduced accordingly, the destabilizing factor of welding It is corresponding to reduce, reduce maintenance cost.

11) due to top layer strip line employ one point of four scheme (i.e. five―port network be divided into four 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.Such as the antenna for base station of the feeding network design based on an input and 12 output ports With 12 radiators, its top layer strip line only has three independent five―port networks and lower floor's feeding network.For One has its length of the antenna for base station of 12 radiators at least will be more than 2.5 meters, if top layer strip line is one point of four directions Case, relative to the prior art, bottom banding line length will reduce, and so advantageously reduce difficulty of processing, reduce the system of strip line Cause this.

12) relative to the prior art, for one point of four scheme since the number of transmission line is reduced, when work, advantageously reduces electromagnetism The leakage of ripple, reduces coupling, improves S parameter, improve performance.
