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, also, each interelement of traditional array antenna is by cable connection in the conductor cavity.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 it sets 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, can be very good to reduce the thickness of antenna entirety in this way, this design will make our antenna Antenna thickness than 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 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 pad for making antenna is excessive, and wiring is extremely complex, and therefore, the production process of antenna for base station needs a large amount 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 consistency 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) the utility model upper strata feeding network includes four port networks and four three-port networks, shares 11 The output port of antenna oscillator can be connected；Due to there are four three-port network, in the case where meeting element number requirement so that connection phase shift The antenna directivity of device is more preferable.
