摘要

在这封信中，提出了一个宽带同轴到充气波导的过渡，这是由衬底集成波导(SIW)技术实现的。目前的设计包含了几个不同孔径的充气通孔，以有效地匹配主要TE10模式下宽工作带宽上的阻抗，从而取代了对介电锥度或更大占地面积的需求。设计并测试了一个转换原型以验证结果。在目标频段(9.5-15 GHz)上，测量到的回波损耗优于15 dB，插入损耗为1±0.1 dB，因此描述了所提出设计的近倍频程带宽。

A Coaxial to Air-Filled Substrate Integrated Waveguide Transition With Near-Octave Bandwidth

In this letter, a wideband coaxial to air-filled waveguide transition is proposed, which has been realized by the substrate integrated waveguide (SIW) technology. The present design incorporates several air-filled vias of varying hole diameter to efficiently match the impedance over a wide operating bandwidth in the dominant TE10 mode, hence replacing the need for dielectric taper or larger footprint. A transition prototype has been designed and tested to validate the results. The measured return loss is better than 15 dB and insertion loss of 1 ± 0.1 dB over the band of interest (9.5–15 GHz), hence portraying a near-octave bandwidth from the proposed design.

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.
