Abstract
The invention discloses a kind of improved all channel antenna, including waveguide segment and loudspeaker section, waveguide segment to be connected with loudspeaker section, has waveguide cavity in waveguide segment, and 23 ridge-like structures are respectively distributed with the upper lower wall in waveguide cavity.The present invention respectively sets up ridge-like structure by the upper lower wall in waveguide cavity, to WAVEGUIDE LOADED, can reduce the bandwidth of operation of cut-off frequency increase waveguide.
Description
Technical field
The present invention relates to field of antenna, and in particular to a kind of improved all channel antenna.
Background technology
Electromagnetic horn is surface antenna, the circle or the microwave antenna of square-section that the gradual change of waveguide tube terminal is opened, is to use
Widest a kind of microwave antenna.Its radiation field is to be determined by the mouth face size of loudspeaker with mode of propagation.Wherein, loudspeaker wall
Radiation is influenceed to be calculated using the principle of geometry diffraction.If the length of loudspeaker keeps constant, mouth face chi
It is very little to increase with quadratic phase difference with the increase of horn flare angle, but gain then will not be with mouth face change in size.If
The frequency band of extension loudspeaker is needed, then needs to reduce horn throat and the reflection at mouth face；Reflection can be anti-with mouth face larger
And reduce.Electromagnetic horn it is relatively simple for structure, directional diagram is also fairly simple and is easily controlled, generally as medium directivity day
Line.Bandwidth, secondary lobe are low and the parabolic reflector electromagnetic horn of efficiency high is usually used in microwave radio relay communication.
According to the actual requirements, it is necessary to which the bandwidth progress to antenna is broadening.
The content of the invention
Present invention aims at a kind of improved all channel antenna is provided, the antenna is each by the upper lower wall in waveguide cavity
Ridge-like structure is set up, the bandwidth of operation of cut-off frequency increase waveguide to WAVEGUIDE LOADED, can be reduced.
The present invention is achieved through the following technical solutions：
A kind of improved all channel antenna, including waveguide segment and loudspeaker section, waveguide segment are connected with loudspeaker section, have in waveguide segment
There is a waveguide cavity, 2-3 ridge-like structure is respectively distributed with the upper lower wall in waveguide cavity.
Each ridge-like structure is wedge shape.Ridge-like structure is arranged to wedge shape, it is possible to increase antenna gain, reduce loss.
Adapter cavity is additionally provided with waveguide segment, adapter cavity is arranged between waveguide cavity and loudspeaker section.
Annular protrusion is provided with adapter cavity.Annular protrusion is set in adapter cavity and can reduce edge diffraction, reduces and intersects
Polarization.
Ridge-like structure is extended in adapter cavity.
2-3 ridge-like structure Heterogeneous Permutation in waveguide cavity.Bandwidth can be increased by shifting to install.
The present invention compared with prior art, has the following advantages and advantages：
The present invention respectively sets up ridge-like structure by the upper lower wall in waveguide cavity, can reduce cutoff frequency to WAVEGUIDE LOADED
Rate increases the bandwidth of operation of waveguide.
