Abstract
The invention discloses a kind of high-gain horn antenna, including waveguide segment, conical section and loudspeaker section, waveguide segment to be connected with conical section, and conical section is connected with loudspeaker section, ridge-like structure is provided with waveguide segment, and ridge-like structure extends to conical section from waveguide segment.The ridge-like structure being arranged in waveguide segment is extended to conical section, can expand antenna gain, reduce the loss in loudspeaker section by the present invention by setting conical section between waveguide segment, loudspeaker section.
Description
Technical field
The present invention relates to field of antenna, and in particular to a kind of high-gain horn 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.
It is one of pursuit of electromagnetic horn that high-gain, which can be obtained,.
The content of the invention
It is an object of the invention to provide a kind of high-gain horn antenna, is justified by being set between waveguide segment, loudspeaker section
Section is bored, the ridge-like structure being arranged in waveguide segment is extended into conical section, antenna gain can be expanded, reduces the damage in loudspeaker section
Consumption.
The present invention is achieved through the following technical solutions：
A kind of high-gain horn antenna, including waveguide segment, conical section and loudspeaker section, waveguide segment are connected with conical section, circular cone
Section is connected with loudspeaker section, ridge-like structure is provided with waveguide segment, and ridge-like structure extends to conical section from waveguide segment.
Multiple gaps are provided with waveguide segment.
Multiple gaps are divided into multiple row and are arranged on waveguide segment outer wall.
Adjacent row form splayed two-by-two.
Gap Heterogeneous Permutation on adjacent row two-by-two.
By setting conical section between waveguide segment, loudspeaker section in the present invention, the ridge-like structure that will be arranged in waveguide segment
Conical section is extended to, antenna gain can be expanded, reduces the loss in loudspeaker section.Multiple gaps, energy are provided with waveguide segment
Enough improve antenna gain.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is prolonged the ridge-like structure being arranged in waveguide segment by setting conical section between waveguide segment, loudspeaker section
Conical section is reached, antenna gain can be expanded, reduces the loss in loudspeaker section.
