Abstract

In this letter, a novel wideband microstrip to additively fabricated waveguide transition is presented. The proposed design takes advantage of the flexibility of 3-D printing to realize a highly integrated transition from the microstrip line on a printed circuit board (PCB) to an air-filled waveguide using an additively manufactured radiating probe. The idea is experimentally verified by the realization of an exemplary transition working within the X-band at

$f_{0} =10.5$

GHz. The measured performance of the back-to-back transition proves its usefulness and possibility of utilization in highly integrated PCB-waveguide circuits. A PolyJet printing technology with copper electroplating was used in combination with PCB on microwave grade laminate. A bandwidth of

$f_{H}/f_{L} =1.8$

was obtained with the impedance match better than 9.5 dB and in-band insertion loss per transition below 1.1 dB.

利用辐射探针实现宽带微带到三维打印充气波导的过渡

在这封信中，提出了一种新的宽带微带到附加制造的波导过渡。所提出的设计利用了3D打印的灵活性，使用额外制造的辐射探针实现了从印刷电路板（PCB）上的微带线到充气波导的高度集成过渡。通过实现在$f_{0}＝10.5$GHz的X波段内工作的示例性跃迁，实验验证了这一想法。背对背转换的测量性能证明了它在高度集成的PCB波导电路中的实用性和应用可能性。在微波级层压板上结合PCB使用了电镀铜的PolyJet印刷技术。获得了$f_{H}/f_{L}=1.8$的带宽，阻抗匹配优于9.5dB，每次跃迁的带内插入损耗低于1.1dB。

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.
