Abstract

The letter demonstrates a coaxial transmission line-to-substrate integrated waveguide (CT-SIW) transition using aperture-coupling approach. The method broadens the bandwidth (BW) and reduces the transition insertion loss (IL). Two coaxial line supports with apertures for coupling are attached at the ends of substrate integrated waveguide (SIW). The copper inlaid of the apertures increases coupling of the coaxial line to SIW and can be controlled by the aperture length and the length of the line wire put in the aperture. The transition was designed, fabricated, and experimentally evaluated. The transition provides the measured 10 dB return loss (RL) fractional BW (FBW) of 104.3%, and 15 dB RL (FBW) of 78.06%. The IL of 0.37 to 0.87 dB at 19.63–62.7 GHz frequency range was obtained. The measured results are well correlated with the simulated ones.

利用孔径耦合方法实现宽带同轴线到SIW的转换

这封信展示了使用孔径耦合方法的同轴传输线到衬底集成波导（CT-SIW）的转换。该方法拓宽了带宽（BW）并降低了转换插入损耗（IL）。在衬底集成波导（SIW）的末端连接两个具有用于耦合的孔的同轴线支架。孔的铜镶嵌增加了同轴线与SIW的耦合，并且可以通过孔长度和放入孔中的线路导线的长度来控制。对过渡进行了设计、制造和实验评估。该跃迁提供了104.3%的测量的10dB回波损耗（RL）分数BW（FBW）和78.06%的15dB RL（FBW）。在19.63–62.7 GHz频率范围内获得了0.37至0.87 dB的IL。测量结果与模拟结果有很好的相关性。

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.
