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 The in vivo feeding network component of conductor chamber 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 entire phase shifter.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 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 in antenna for base station design when, the oscillator and phase shifter of antenna, between phase shifter internal element 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, 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) 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, 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, 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 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- It penetrates 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 independent from each other, and reflecting plate and phase shifter are all independent from each other component 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) in phaser cavity, so can be very good to reduce the thickness of antenna entirety, this design will make our antenna Antenna thickness than any rival is all thin, and the size and volume of so entire antenna will become smaller, 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 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, the welding point for making antenna is excessive, and 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, it is 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 It writes and improves production efficiency.

9) lower floor's feeding network of the present invention includes a first input port and five the first output ports；Upper strata transmission network Network includes three four port networks and two three-port networks, and each four port network includes three second output terminal mouths and with one Second input port that a first output port is connected by transmission line；Each three-port network includes two second outputs Port and second input port being connected with first output port by transmission line.Connect levels feeding network Transmission line number is five, and whole network will form one one point 13 of network after levels feeding network is connected, i.e., One input and 13 output ports.Due to there are five transmission lines, correspondingly, process to accommodate transmission line on cavity Number of windows also only there are five, can so reduce CNC processing capacities, reduce processing cost.

10) since top layer strip line employs the scheme of four port networks and three-port network combination, difference can be met and shaken The advantages of demand of subnumber phase shifter, existing four port network, and the good directivity of three-port network is combined, there is structure Simply, solder joint is few, and manufacturing process is simpler, is effectively reduced cost, improves antenna gain.
