“…We have developed spectrum analyzer in the frequency domain over 100 GHz, which is necessary to develop the aforementioned technologies. As its preselector, we have proposed a novel tunable filter which constitutes a Fabry–Perot resonator inside waveguide (FPW filter) . As the center frequency of the transmissive range for this filter is determined only by the distance between two half‐mirrors mounted inside waveguide, wide frequency tuning range can be realized in principle.…”

SUMMARY For the realization of the smart community, the Internet of Things (IoT) and sensor technology in the millimeter‐wave band is necessary. The development of these technologies requires accurate spectrum analysis in the frequency domain over 100 GHz. A tunable preselection filter is a key device in building such a spectrum analyzer. In this paper, we propose use of a ridge waveguide to achieve frequency tuning over a wider bandwidth. In addition, we demonstrate an example design and prototype for a filter with a relative bandwidth of 38% (75 GHz to 110 GHz) and 32% (78.1 GHz to 107.5 GHz), respectively.
