Abstract

This letter presents a broadband 90° bent waveguide transition that is suitable for the $H$ -plane split-blocks technique. In this transition, imperfect metal connections will not cause unacceptable transmission loss by employing a novel U-shaped choke groove and a groove gap waveguide. Such contactless waveguide transitions are advantageous as they allow for easy interconnection and packaging of millimeter-wave and terahertz circuitry. A 90° bent waveguide operating over the WR-4.3 waveguide frequency band (170–260 GHz) is designed, and the transition with a different air gap between the top and bottom parts is measured. The measured results show that the transmission losses are about 0.2 dB with good consistency.

带U形扼流槽的宽带90°非接触波导过渡

这封信介绍了一种适用于$H$-平面分裂块技术的宽带90°弯曲波导过渡。在这种过渡中，通过采用新型的U形扼流槽和槽隙波导，不完美的金属连接不会导致不可接受的传输损耗。这种非接触波导转换是有利的，因为它们允许毫米波和太赫兹电路的容易互连和封装。设计了一个在WR-4.3波导频带（170–260 GHz）上工作的90°弯曲波导，并测量了顶部和底部之间具有不同气隙的过渡。测量结果表明，传输损耗约为0.2dB，具有良好的一致性。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
