采用厚膜SU 8光刻胶工艺设计并制作了一种工作频率为28 ~ 48 GHz的新型矩形同轴电缆。提出了两对弯曲的四分之一波长支撑短截线来减小结构的横向尺寸。与采用直支撑短柱设计的类似结构相比，采用弯曲支撑短柱设计的结构尺寸减小了40%。在28 - 48 GHz带宽范围内，平均插入损耗为0.36 dB，回波损耗优于− 14 dB。使用弯曲的支撑短截线并不影响其微波性能。因此，该组件对于诸如复杂耦合器或Butler矩阵之类的集成组件特别有吸引力，其中整体尺寸减小（没有性能损失）和成本节省可以是实质性的。© 2008 Wiley Periodicals，Inc.

A new type of rectangular coaxial cable, operating from 28 to 48 GHz, was designed and fabricated with thick SU8 photoresist technology. Two pairs of bent quarter‐wavelength supporting stubs were proposed to reduce the lateral dimension of the structure. A size reduction of 40% was achieved by using the bent supporting stubs design as compared with a similar one with straight supporting stubs design. An average insertion loss of 0.36 dB across the bandwidth of 28‐48 GHz was achieved, with return loss of better than − 14 dB. The use of bent supporting stubs did not compromise its microwave performance. The component is, therefore, particularly appealing for integrated components such as complex couplers or Butler matrix, where overall size reduction (with no loss of performance) and cost saving can be substantial. © 2008 Wiley Periodicals, Inc.
