Abstract
The utility model provides a converter for square-waveguide and circular groove waveguide, which comprises a converter for rectangular waveguide and circular waveguide and a converter for circular waveguide and circular groove guide. The circular waveguide end faces of the two converters forms a whole through fixed connection. The circular waveguide and circular groove waveguide converter is composed of two blocks of wedge-shaped metal plates separated off by upper and lower insulating strips, and a round table shaped through hole is arranged at the symmetric center position along the metalplates direction. The utility model has the advantages of low wastage and color dispersion, large transmission power capacity, etc. which is convenient for the connection between a rectangular waveguide system and a circular groove waveguide system.
Description
The utility model is a kind of waveguide component of changing between rectangular waveguide and the circular recess wave guide of being used for, and belongs to millimeter wave, submillimeter wave technical field.
The transmission line of microwave band and light-wave band has many researchs, millimeter wave between these two wave bands, submillimeter wave is then developed laterly, especially short millimeter and submillimeter region, short millimeter, the novel transmission line of submillimeter wave are all being sought to be suitable in countries in the world at present.In the prior art, short millimeter band also adopts the standard rectangular waveguide usually, but loss is very big; Submillimeter region often adopts beam waveguide, but physical dimension is too huge, assembles, debugs also very difficult; The rectangular channel waveguide because the energy output device of gyrotron is a circular waveguide, did not also propose rectangular waveguide---circular recess wave guide transducer because it is not easy to be connected and experience difficulties with the gyrotron that can export great power now at present.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of high-power millimeter wave that is suitable for transmitting, the waveguide component that uses in the circular recess wave guide system of submillimeter wave: rectangular waveguide---circular recess wave guide transducer.
The utility model forms according to mode conversion theory and circular recess wave guide Design Theory.Its stereochemical structure, as shown in Figure 1, it is made up of two parts; First is rectangular waveguide and circular waveguide transducer, second portion is circular waveguide and circular recess wave guide transducer, one end of rectangular waveguide and circular waveguide transducer is the rectangular waveguide cross section, the other end is that the circular waveguide cross section is the linearity transition between them, promptly is connected with straight line between the respective point on the every bit on the rectangle perimeter and the circumference and the space that constitutes.One end of circular waveguide and circular recess wave guide transducer is the circular waveguide cross section, the other end is the circular recess wave guide cross section, it is made of two metallic plates that the upper and lower insulation strip that is wedge shape separates, truncated cone-shaped through hole along the metallic plate length direction is arranged in the symmetrical centre position of its end face, and the circular waveguide end face of two transducers constitutes one by fixedly connected.Circular waveguide and circular recess wave guide transducer also can open with " V " font for the vertical center line of one end from the circular section, the maximum open place of " V " font, distance equals the distance between circular recess wave guide two metal plates between 2, at the square-section end rectangular waveguide flange is housed, on the wall of the waveguide limit of circular recess wave guide end, is provided with connecting hole.
The utility model is based upon on the circular recess wave guide transmission theory basis, compared with prior art, has low-loss, low chromatic dispersion, and the waveguide cross-section size is big, and the power capacity of transmission is big.The little order of magnitude of the standard rectangular waveguide that its loss ratio is traditional, cross sectional dimensions is bigger 6～8 times than the standard rectangular waveguide under the same frequency, easily processing.At short millimeter band, a large amount of signal sources in the laboratory all are rectangular waveguide output at present.The utility model can be the electromagnetic wave that transmits in the original rectangular waveguide, is transformed in the circular recess wave guide of much lower times of loss and goes transmission, to reach the purpose that reduces the wastage; Another kind of situation is, instrument and equipment in the present laboratory, all be suitable for connecting rectangular waveguide, also wish conveniently and to utilize existing each company economically as the circular recess wave guide system, therefore the various instrument and equipments that producer has produced all need the utility model and set up " bridge " between rectangular waveguide and two kinds of Wave guide systems of circular recess wave guide.The utility model is that other all existing elements can't replace.
Fig. 1 is the utility model perspective view, and Fig. 2 is a generalized section.
