“…Comparing the known microwave filters with a minimum of losses (with the same bandwidth or barrier), then it is possible to note, the waveguide filters have the best intrinsic quality factor [10]- [15]. This is explained by the fact that in the centimeter wavelength range, the waveguide (WR) and waveguide-dielectric resonators (WDR) [16]- [19] have the greatest natural quality factor. Waveguide filters have proven themselves in stationary equipment, where the requirements of minimum signal loss are more important than mass and dimensional parameters.…”

Design narrow-band compact filters, based on high-quality waveguide-dielectric resonators with anisotropic materials is the subject of this paper. Filter represents a segment of a rectangular waveguide rotated around the longitudinal axis of the waveguide 90 degrees and containing one or more dielectric inserts that completely fill the resonator along the narrow wall of the waveguide and partially along the wide one. A distinctive feature of the proposed filter is higher slope steepness of the amplitude-frequency characteristic, and high manufacturability in the centimeter range. The designed narrow-band filter satisfies contradictory requirements: it combines narrow bandwidth (≈ 0.1% of center frequency <em>f</em><sub>0</sub>) with low passband insertion loss (≤ 1 dB).
