MATCHING DEVICE FOR TWO DIFFERENT-RANGE RECTANGULAR WAVEGUIDES WITH COMBINED COAXIAL AND CIRCULAR WAVEGUIDES Russian patent published in 2022 - IPC H01Q5/10 

FIELD: microwave technology.

SUBSTANCE: invention relates to microwave technology and is intended for matching two multi-band rectangular waveguides with a combined coaxial and circular waveguides. The device can be used in irradiators of parabolic antennas of communication systems, radar, radio navigation, various measuring and special radio equipment. The matching device of two different-range rectangular waveguides with combined coaxial and circular waveguides contains a coaxial-circular waveguide, two input/output rectangular waveguides, one of which is designed to transmit microwave signals at low frequency, and the second at high frequency, the novelty is that the device includes a transition from a high-frequency rectangular waveguide to a circular one, with the output of which a round waveguide is connected, which is simultaneously the central conductor of the coaxial line of the low-frequency range and is fixed inside the high-frequency section of the device, which has a cylindrical part with a cut at an angle of 45°, which is inserted into the opening of the combining section of the device, and the cut of the cylindrical part of the high-frequency section is located opposite the rectangular window in the combining section, to which the low-frequency rectangular waveguide of the device is connected, on which a screw is placed that regulates the degree of matching of the waveguides.

EFFECT: simplifying the design and providing the ability to adjust the device to match the load.
