Abstract

The invention discloses a method and device for realizing specific orientation of a beam. The device includes a fan-shaped waveguide set composed of a plurality of equally spaced arc curved waveguides, wherein circle centers of the arc curved waveguides coincide at one point, the fan-shaped waveguide set performs slot feeding through a plurality of straight waveguides as feed waveguides, the straight waveguides are perpendicularly connected to the arc curved waveguides, and extension lines of the straight waveguides intersect the circle centers of the arc curved waveguides. The device is advantaged in that fixed phase difference between azimuth plane elements is realized by the equally spaced fan-shaped waveguide set in combination with the straight waveguides for slot feeding, so specificorientation of the beam is realized; the straight waveguides for feeding are loaded at different locations in the fan-shaped waveguide set, fixed phase difference between different array elements canbe realized, and multi-beam orientations are conveniently realized.

Description

technical field [0001] The present invention relates to the field of microwave communication, in particular to a method and device for realizing specific orientation of beams. Background technique [0002] A multi-beam antenna is an antenna that can generate multiple sharp beams. Due to its ability to communicate with multiple targets at the same time, it can achieve wide-area coverage with one antenna, and each beam can achieve high gain. and other fields have broad application prospects. Multi-beam antennas mainly include lens multi-beam, reflector multi-beam and phased array multi-beam. The structure of the former two is complex, and the number of multi-beams is limited due to problems such as defocusing, while phased array multi-beam can adjust the number and shape of beams. Flexible control, more and more widely used in the fields of satellite communication and electronic countermeasures. The traditional multi-beam phased array mainly realizes the amplitude and phase ...
