Background technology
With the development of the communication technology, for the requirement more and more higher of communication network quality.Modern communicationses are required to meet
Round-the-clock, no blind spot no dead angle, therefore for communication link, just not only requires nothing more than signal transacting and the signal identification of rear end
Hypersensitivity, ultralow time delay can be accomplished, also the hardware device of front end is proposed with the use requirement under various special screnes, with
Guarantee that the advanced communication technology can be ubiquitous.Therefore three-dimensional figure possesses the feature of sector, can be real in polarizers of big angle scope
Existing signal is reported, and can support that the microwave fan anteena of point-to-multipoint also begins to show out its advantage especially.
At present on the implementation of fan anteena, majority is thrown using E-plane sectored horn, feed forward type horn illumination, tradition
The modes such as object plane cutting are realized.E-plane sectored horn mainly uses the general principle of electromagnetic horn, by narrowing on certain direction
Size, and adopt some choke structures, thus realizing Sectored antenna basic function, but the directionality of such antenna is not strong,
The antenna of high-gain cannot be realized.Feed forward type horn illumination and traditional parabola cutting fan anteena are then mainly most of by four
Composition：The part such as reflective surface portion, feed part, antenna shield, mounting hung rack part forms, and substantially, feed is exactly individual
Primary antenna, can be to be designed using different forms, and the primary pattern that major control feed is formed, for shadow surface
Antenna.Reflecting surface is then the spherical wave being irradiated to feed on face, reflects away, using parabolical general principle in surface antenna
Actinal surface form constant amplitude, homophase and obtain plane wave re-radiation and go out.Antenna house and mounting hung rack are then if being used for protecting antenna simultaneously
Realize the mechanical function of antenna.
Feed forward type horn illumination, traditional parabola cut the feed of antenna sector typically directly by standard dish
Directly development forms feed, and it is difficult to arbitrarily to form E face or H face according to the requirement of integrated antenna design and obtains narrow beam, and H face
Or E face is broad beam.Therefore also just it is difficult to for the directional diagram of integrated antenna, the control of gain and design.
Traditional feed is typically made up of parts such as radiating horn, transmission waveguide and feed fixed seats, and it is typically all
Fixed by gluing, version requires it to need accurately to position；Radiation head mainly by media fraction with for reflection metal
Piece forms, and both are made of one, and is typically fastened with riveting or screw, assembling is complicated, and efficiency is very low, and qualification rate is not high；Improve
After technique, electroplate layer of metal typically on medium, then spray protective paint, but plating is big for environment pollution, and both the above side
, with the rising of usage frequency, size is less and less for method, and precision also requires that more and more higher, substantially cannot operate.
