Compact bandpass filters are being developed using Möbius wire-loaded cavity resonators. Initial results on tuned filters indicate that excellent filter characteristics can be attained in devices that are significantly smaller than traditional wire-loaded cavity technologies. A novel quad-mode Möbius resonator is presented which occupies the same volume as a dual-mode Möbius resonator. A four-pole bandpass filter is demonstrated using a single quad-mode Möbius resonator. Precisely controlled dielectric loading of dual-mode Möbius wire resonators has been implemented to realize bandpass filters. Two-pole and four-pole bandpass filters are demonstrated using one and two dual-mode dielectric-loaded Möbius resonators, respectively.
