Description

Horn antenna capable of being automatically adjusted at multiple angles

Technical Field

The utility model relates to the technical field of horn antennas, in particular to a horn antenna capable of being automatically adjusted in multiple angles.

Background

The horn antenna is a surface antenna, and a microwave antenna with a circular or rectangular section with a gradually-changed and opened waveguide tube terminal is the most widely used microwave antenna. Its radiation field is determined by the size and propagation type of the horn. The influence of the horn wall on the radiation can be calculated by using the principle of geometric diffraction. If the length of the horn is kept constant, the difference between the square phase and the mouth surface size increases with the increase of the flare angle, but the gain does not change with the mouth surface size. If the frequency band of the horn needs to be expanded, the reflection at the neck and the mouth of the horn needs to be reduced; the reflection will decrease as the size of the oral surface increases. The horn antenna has a relatively simple structure, and a directional pattern is relatively simple and easy to control, and is generally used as a medium-directivity antenna. The parabolic reflector horn antenna with wide frequency band, low side lobe and high efficiency is commonly used for microwave relay communication.

However, it is inconvenient to adjust the inclination angle and the horizontal angle of the horn antenna at present, and the practicability is poor, so we propose a horn antenna capable of multi-angle automatic adjustment for solving the above problems.
