A Novel Design Technique for mm-Wave Mismatch Terminations

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.
