Problems solved by technology

[0004] Traditional rectangular waveguide couplers mostly use porous coupling methods in order to obtain a wider operating bandwidth, and at the same time increase the number of coupling holes to improve the coupling flatness, but this also leads to the larger size of traditional directional couplers and high processing accuracy requirements , high insertion loss

Abstract

The invention discloses a compact broadband rectangular waveguide coupler, relates to the technical field of microwave and millimeter wave devices, and specifically relates to a compact broadband rectangular waveguide coupler. In order to broaden the working bandwidth of the rectangular waveguide and improve the flatness of the coupler coupling, the present invention proposes a compact broadband rectangular waveguide coupler; different from the traditional waveguide coupler, the rectangular waveguide coupler uses a coupling array composed of square holes and narrow slits Not only the structure of the coupler is compact and easy to process, but also the coupling fluctuation realized in the working frequency band (26.5GHz-40GHz) is lower than 0.3dB. The coupling hole array composed of square small holes and narrow slits is adopted, and the structure is simple, so that the overall structure of the coupler is compact and the processing is simple.

Description

technical field [0001] The invention relates to the technical field of microwave and millimeter wave devices, in particular to a compact broadband rectangular waveguide coupler. Background technique [0002] Rectangular waveguide couplers have a wide range of applications in microwave wireless communication systems, microwave on-line measurement, radar reflection monitoring, broadband high-power attenuation and other fields. Its main function is to accurately sample the energy transmitted in the microwave system, and extract a part of the microwave energy, so that the energy transmitted in the microwave system can be monitored by the time domain envelope, power measurement, spectrum measurement, etc. With the continuous development of microwave technology, the demand for waveguide couplers is also changing and improving. In order to meet the different needs of the development of electronic equipment, rectangular waveguide couplers have also developed from single-hole coupl...
