| 摘要: |
| 介绍了一种新型的宽带波导-微带对脊鳍线过渡设计。它利用对脊鳍线自身结构的调整,就可以对频带内谐振频率产生抑制作用,不需外加任何谐振抑制结构或金属孤岛,减少了设计和制造的复杂性。这种紧凑的过渡模型不仅结构简单、尺寸短小,而且可以在宽频带范围内实现较低的插入损耗和回波损耗,方便工程上的应用。对实验样品的测试表明,在Ka全频段内其插入损耗小于0.8 dB。 |

| Abstract: |
| This paper presents a design of waveguide-to-microstrip antipodal finline transition,which provides a broadband performance without any additional resonance frequency preventer in the model.The suppression of resonance frequency depends on the self-structure of the antipodal finline transition,and it requires no extra components as resonance preventers,which decreases the difficulty of design and manufacture.This compact transition has low insertion loss,low reflection performance in wide band,as well as small and compact structure size.It is useful in engineering application.Simulation and sample measurement shows that the insertion loss is less than 0.8dB in Ka band. |
