Embodiment Construction

[0029] Since ordinary dielectric Lunberg lenses require multi-layer dielectric combinations to achieve the characteristics of graded dielectric constant, this feature leads to complex processing, and the gap between multi-layer dielectrics will cause greater loss. There is no problem of gap loss between layers in the Luneberg lens with air medium. The air medium Luneberg lens not only provides stable characteristics, but also the lens part is only air, and the rest is metal, which greatly improves the ease of processing. Another consideration is that the volume of a complete air lens is too large, which is inconvenient for processing and practical application, so the required parts are kept and the parts that cannot be reached by the signal are removed, forming such as image 3 and Image 6 In the shape shown, the upper and lower sides of the lens are cut with curved surfaces to ensure the required equivalent dielectric constant.

Abstract

The invention discloses a space power divider / combiner. A disc-shaped air column lens adopts a metal disc-shaped parallel plate waveguide comprising an upper metal disc layer and a lower metal disc layer; upper and lower inner surfaces of the metal disc-shaped parallel plate waveguide adopt arc surfaces; a long side of a standard rectangular waveguide is perpendicular to the metal discs of the disc-shaped air column lens; a transition waveguide is in a horn mouth shape; one end of the transition waveguide is connected with the standard rectangular waveguide; the other end of the transition waveguide is intersected with the disc-shaped air column lens; an output end surface of a U-shaped output array is rectangular; an input end surface of the U-shaped output array adopts a semicircular arc surface matched with the disc-shaped air column lens; and a plurality of parallel metal baffles which are perpendicular to the metal discs of the disc-shaped air column lens are arranged in the U-shaped output array. The space power divider / combiner has high output power, wide frequency band and high combined efficiency, and has the advantages that the structure is simple, the processing accuracy requirement is low, the manufacture cost is low, the expansibility is high, heat emission is easy to realize, and the like.

Description

technical field [0001] The present invention relates to a power divider / combiner, in particular to a spatial power divider / combiner. Background technique [0002] In the microwave and millimeter-wave frequency range, a variety of power combining techniques have been proposed in recent decades. Quasi-optical (spatial) power combining technology is a power combining method proposed in the early 1980s. In this quasi-optical or spatial power synthesis, the power is coupled into a large-diameter guided wave beam by an active device, and then focused by the beam to the space power demand or converted into a waveguide mode for output. The large diameter beam cross-section allows a larger number of combining elements to be used, thus providing greater output power. And all synthesis units are in parallel working state, so the loss is basically independent of the number of synthesis units, which makes the spatial power synthesis have a very obvious advantage when the number of synt...
