The mismatch terminations are essential components in measurement setups of various active and passive microwave components. The main objective of such components is to provide a certain reflection level with a flat response over the operating bandwidth. The need for mm-wave mismatch terminations has increased due to the expansion of using mm-wave frequency ranges in future communication systems. The mm-wave bands are considered among the essential bands for the 5G communication system, which is expected to launch this year. In addition, the utilization of these bands is expected to increase in the 6G standard. In this article, we introduce a novel systematic procedure to design mismatch terminations. Moreover, two examples of mismatch terminations are designed with reflection levels of −9.5 and −12.7 dB, with the operating band of 32–38 GHz. For experimental validation, the proposed design is fabricated and measured, where a good agreement is achieved between the simulated and the measured response.

毫米波失配终端的新型设计技术

失配终端是各种有源和无源微波组件的测量设置中必不可少的组件。这种组件的主要目的是提供一定的反射水平，并在整个工作带宽上具有平坦的响应。由于在未来的通信系统中使用毫米波频率范围的扩大，对毫米波失配终端的需求增加了。毫米波频段被认为是有望在今年推出的5G通信系统的重要频段之一。此外，在6G标准中，这些频段的利用率有望提高。在本文中，我们介绍了一种新颖的系统过程来设计失配终端。此外，设计了两个失配终端的示例，其反射电平为−9.5和-12.7 dB，工作频带为32–38 GHz。
