A novel design technique for mm-wave mismatch terminations

The mismatch terminations are essential compo-
nents 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 mis-
match 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.
