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 (surface of conductor housing) and the public face of phase shifter conductor cavity, two Person is not mutually independent, and reflecting plate and phase shifter are all mutually independent components 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 thickness of antenna entirety, this design will make our antenna All thinner than the antenna thickness of any rival, 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 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) the utility model upper strata feeding network uses five four port networks (three output ports and an input terminals Mouthful), lower floor's supply network road includes an input port and five output ports, and levels feeding network is connected using transmission line, Solder joint is reduced, the destabilizing factor of welding also reduces accordingly, reduces maintenance cost；It can be connected with 15 output ports 15 radiators, the phase shifter based on four port networks improve gain and the directionality of antenna.About 1.6 meters of antenna, highest increase Benefit reaches 20.5dBi.
