Abstract
The utility model provides a circular groove waveguide matched load, which is a waveguide element used for a circular groove guide system. The circular groove waveguide matched load is composed of waveguide and dielectric material absorbing electromagnetic, wherein, the waveguide is compose of upper and lower two blocks of metal plates separated off by insulating strips; a circular through hole is arranged on the symmetric center position of the end surface of the metal plates along the length direction of the metal plates; the dielectric material can be made into splitter-shaped electromagnetic wave absorbing pieces or awl splitting gradual deformation electromagnetic wave absorbing body according to the power. The utility model has the advantages of low wastage, small color dispersion, large waveguide cross-sectional dimension, large transmission power capacity, etc. which is suitable for transmitting short millimeter-wave and sub-millimeter wave.
Description
The utility model is a kind of waveguide component that is used for the circular recess wave guide system, belongs to millimeter wave, submillimeter wave technical field.
The transmission line of microwave band and light-wave band has many researchs, and millimeter wave, the submillimeter wave wave band of boundary between this two wave band then developed laterly, especially short millimeter and submillimeter region.At present countries in the world all at the novel transmission line of seeking to be suitable for short millimeter and submillimeter wave, at short millimeter band, adopt the standard rectangular waveguide usually, but loss are very big, and to be not easy to exporting energy device be that the gyrotron of circular waveguide is connected; In submillimeter region, adopt metric wave to lead usually, but physical dimension is too huge, assemble, debug also very difficult.Also do not have at present to be used for short millimeter band, can be used for the load of submillimeter region power match again.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of power match load that is suitable for millimeter wave and submillimeter wave is provided, and it is convenient to directly be connected with the gyrotron that can export great power.
The utility model designs according to the circular recess wave guide transmission theory, it is made up of waveguide and the electromagnetic dielectric material of absorption, be characterized in two metal plates formations that waveguide is adopted has insulation strip to separate up and down, in the symmetrical centre position of its end face a manhole along the metal plate length direction is arranged, absorb electromagnetic dielectric material and place the waveguide inside terminals, and link together with the waveguide end cap.For the ease of the connection between the waveguide component, on the wall of waveguide other end limit, be provided with connecting hole.Absorb the electromagnetic wave dielectric material and can make different version according to the size of through-put power.
The utility model compared with prior art owing to adopt the circular recess wave guide structure, it is low to have a loss, chromatic dispersion is little, the waveguide cross-section size is big, the power capacity of transmission is big, is convenient to and produces advantages such as the gyrotron of lacking millimeter wave, submillimeter wave great power is connected.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, and the power capacity of transmission is than the big manyfold of standard rectangular waveguide.The utility model both had been suitable for the power match load as short millimeter wave, also can be used as the power match load of submillimeter wave, and it is particularly suitable for the high power transmission of short millimeter and submillimeter wave.
