摘要
A new structure planar-type dielectric resonator (PDR) with high Q has been developed using an LTCC process. The PDR consists of two different dielectric constant materials, a hollow patch center ground plane in the middle of the cavity layer and shielded cavity metals. The realized PDR shows a high unloaded-Q factor of about 1920 at 34.3 GHz. We also developed a dual mode band-pass filter using the proposed PDR, demonstrating a compact filter at a millimeter-wave hand.
