Body, phase shifting equipment is installed 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 separate, and reflecting plate and phase shifter are all separate parts 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 overall thickness of antenna, 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) because 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, realize that automation is extremely difficult.Because the design has Highgrade integration feature, therefore, 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 has ten output ports, can connect ten antenna oscillators；Levels feeding network is using biography
Defeated line connection, the processing of conductor housing is simpler, and solder joint is few, reduces because welding the unstable failure brought.
