Abstract
The utility model provides an E surface phase correcting pyramid feedhorn, which comprises a waveguide mouth and a waveguide horn body which is formed into integration with the waveguide mouth and has a cross section which is gradually extended. The inner part of the waveguide horn with a gradually extended cross section is provided with at least one flat plate which can cause E surface and H surface directional patterns to be equaled. The utility model has the advantages of simple structure, good equalization of the E surface and the H surface directional patterns, and wide working frequency band.
Description
The utility model relates to a kind of improved pyramidal horn antenna, and particularly a kind of E face phase place is imitated positive pyramidal horn antenna.
Pyramidal horn antenna is one of the most frequently used microwave antenna, generally make radiator, but pyramidal horn antenna since structures shape its radiance relatively poor, E face and H face directional diagram be grade not, therefore in order to improve the radiation characteristic of pyramidal horn antenna, makes changes such as E face and H face directional diagram, and have low level and a good cross polar decoupling performance done, usually all be to adopt multiple pleurodiaphragmatic in terspace to manage to improve the horn antenna characteristic, but multiple pleurodiaphragmatic in terspace reason more complicated, cost is also higher.
The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of improved E face phase place to imitate positive pyramidal horn antenna.
The utility model is the improvement on existing pyramidal horn antenna, it comprises the waveguide trumpet body that waveguide mouth and cross section formed integrally therewith are expanded gradually, and the flat board that a slice at least can make E face and H face directional diagram etc. change is installed in the waveguide trumpet body that the cross section is expanded gradually.
Above-mentioned can to make the flat board of changes such as E face and H face directional diagram be two, and it is vertical with the E face, fixedlys connected with the waveguide trumpet body inwall that the cross section is expanded gradually, can weld or adopt alternate manner to connect.
The utlity model has following characteristics:
1. the utility model gain is high, and frequency characteristic is good, is applicable to that low pair is done the broadband operation area requirement, and owing to simple structure, adjust easily, and length is shorter, so loss is also little.
2. the utility model can be separately as the usefulness of sending and receiving antenna, and the feed that also can be used as reflector antenna makes antenna system configuration simple, and performance improves.
3. E face of the present utility model and H face directional diagram etc. are changed, and with agreement with theoretical calculation, working band is wide.
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 contour structures schematic diagram of the present utility model.
Fig. 2 end view of the present utility model.
Fig. 3 is the profile of Fig. 2 along the A-A section.
Accompanying drawing 1~Fig. 3 has described an embodiment of the present utility model.The waveguide trumpet body (2) that it is expanded gradually by rectangular waveguide mouth (1) and cross section formed integrally therewith is formed, waveguide trumpet body (2) is expanded gradually by the rectangular waveguide cross section and is formed, in waveguide trumpet body (2), have two vertical with the E face, and the flat board (3) that E face and H face directional diagram etc. are changed, dull and stereotyped (3) are welded to connect with the inwall of the waveguide trumpet body (2) that the square-section is expanded gradually.
Claims (2)
1, a kind of E face phase place is imitated positive pyramidal horn antenna, comprise the waveguide trumpet body that waveguide mouth and cross section formed integrally therewith are expanded gradually, the flat board that a slice at least can make E face and H face directional diagram etc. change is installed in the waveguide trumpet body that it is characterized in that expanding gradually in the cross section.
2, E face phase place according to claim 1 is imitated positive pyramidal horn antenna, it is characterized in that described can to make the flat board of changes such as E face and H face directional diagram be two, and it is vertical with the E face, fixedlys connected with the waveguide trumpet body inwall that the cross section is expanded gradually.
