Abstract :
We introduce a novel high-temperature superconductor (HTS)-shielded dual-mode resonator based on the degenerated fundamental mode of a dielectric hemisphere. By employing coupling with electric probes and dual-mode splitting with dielectric rods, we have built an HTS-shielded dual-mode two-pole filter at a center frequency of 6.4 GHz with a bandwidth of 0.4% and an insertion loss of 0.02 dB.
