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 claimed by the present invention is not limited to the scope involved in the examples.

[0028] refer to figure 2 , 3 , 4. The power division horn antenna 1 for spatial power combination 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 wide side of the hollow rectangle. The shaped metal wedge 12 divides the aperture of the power distribution radiation port 11 into two identical parts. The rectangular waveguide is composed of a hollow rectangular metal tube at one end. Its diameter meets the requirements of radiation beam width and antenna gain. At the same time, its width should be greater than twice the wo...

Abstract

The invention discloses a power dividing horn antenna and the related array for spatial power combining. The power dividing horn antenna comprises a power distributing radiation aperture, a matching transition section and a waveguide feed line, which are connected in order and seamlessly to form the antenna; wherein, the power distributing radiation aperture comprises a hollow rectangular waveguide and a shaped metal wedge arranged on the wide edge of the hollow rectangle, and the shaped metal wedge divides the aperture of the hollow rectangular waveguide into two same parts; the power distributing horn antenna array used for spatial power combining comprises at least two power distributing horn antennas arranged together tightly. The invention has the advantages that when being used solely, a power distributing horn can provide a higher gain than a normal horn antenna with the same aperture because of an improved electromagnetic field distribution on the aperture; the power distributing horn antenna array prevents grating lobes from generating when increasing the size of the antenna array, which increases significantly the aperture and gain of the spatial power combining antenna,and the effectiveness of power combining.

Description

technical field [0001] The present invention relates to the technical field of space power synthesis, specifically a power splitter horn and its array for space power synthesis. The power splitter itself can be used as an antenna, and its array can be used as a power combiner antenna or It can be used as a feed array unit of an offset parabolic cylindrical power combining antenna. Background technique [0002] In radar, electronic countermeasures and long-distance communication, it is necessary to obtain high-power directional electromagnetic radiation beams. When a single signal source cannot generate enough power, it is necessary to use a power combining method to combine multiple lower-power signals into the required high-power radiation. There are two methods: one is to use power combining based on circuits or waveguides Technology, the multi-channel signal is combined by the combination network of the circuit or waveguide, and then radiated out through the antenna, but...
