Embodiment Construction

[0027] The preparation of the present invention will be further described below in conjunction with the accompanying drawings and examples, but the scope of protection of the present invention is not limited to the scope involved in the examples.

[0028] Referring to FIGS. 2 , 3 and 4 , the power division horn antenna 1 for spatial power synthesis includes a power distribution radiation port 11 , a matching transition section 13 , and a waveguide feeder 14 . The power distribution radiation port 11 is composed of a hollow rectangular waveguide and a shaped metal wedge 12 welded in the middle of the broad side of the hollow rectangle. The shaped metal wedge 12 divides the aperture of the power distribution radiation port 11 into two equal parts. The rectangular waveguide is composed of a rectangular metal tube with a hollow end. Its diameter meets the requirements of the radiation beam width and antenna gain. At the same time, its width should be greater than one time of the wo...

Abstract

The invention discloses a power-dividing horn antenna and an array thereof for space power synthesis. The power-dividing horn antenna is composed of a power distribution radiation port, a matching transition section, and a waveguide feeder sequentially seamlessly connected; the power distribution radiation port is composed of a hollow rectangular waveguide and a waveguide feeder. It consists of a shaped metal wedge located in the middle of the wide side of the hollow rectangle, and the shaped metal wedge divides the aperture of the hollow rectangular waveguide into two identical parts. The power splitting horn antenna array used for spatial power combining is composed of at least two power splitting horn antennas closely arranged. When the power splitting horn is used alone, due to the improved electromagnetic field distribution on the aperture, it can obtain higher gain than the ordinary horn antenna of the same aperture. The power splitting horn antenna array avoids grating lobes when the size of the antenna array is increased, effectively Increase the caliber of the space power combining antenna, increase the gain of the space power combining antenna, and improve the efficiency of power combining.

Description

technical field [0001] The invention relates to the technical field of space power synthesis, in particular to a power division horn used for space power synthesis and an array thereof. The power division horn itself can be used as an antenna, and its array can be used as a power synthesis antenna or It can be used as the feed array unit of the offset-feed parabolic cylindrical power combining antenna. Background technique [0002] In radar, electronic countermeasures and long-distance communication, high-power directional electromagnetic radiation beams need to be obtained. When a single signal source cannot generate enough power, a power combining method needs to be used to combine multiple low-power signals into the required high-power radiation. There are two methods: one is to use circuit-based or waveguide-based power combining technology, the multi-channel signal is combined with the power of the combined network of circuits or waveguides, and then radiated out throu...
