Abstract
Provided is a dielectric waveguide filter that includes a dielectric main body. A plurality of isolation slots and frequency tuning blind holes are provided in the dielectric main body. At least two port signal transmission holes are further provided in the dielectric main body. The at least two port signal transmission holes and at least part of the plurality of frequency tuning blind holes are disposed on two opposite sides of the dielectric main body. In a thickness direction of the dielectric main body, the at least two port signal transmission holes do not overlap with the at least part of the plurality of frequency tuning blind holes. The dielectric waveguide filter according to embodiments of this disclosure achieves miniaturization while improving out-of-band rejection capability.
