Title:
DIELECTRIC BLOCK BAND-STOP FILTER
Document Type and Number:
WIPO Patent Application WO/2012/118240
Kind Code:
A1
Abstract:
A dielectric block band-stop filter is provided. The dielectric block band-stop filter comprises: a substrate including first and second input/output lines, an inductor connected between the first and second input/output lines, and a ground electrode; a first dielectric block mounted on the substrate, first dielectric block having resonance holes formed in the interior thereof and a plurality of conductive patterns disposed on the surface thereof; and a second dielectric block stacked on the first dielectric block, the second dielectric block having a first electrode pattern disposed thereon. The plurality of conductive patterns comprises: resonator patterns disposed on the inner walls of the resonance holes and on one side of the first dielectric block; an input/output pattern connected to the first and second input/output lines and disposed at least on one side of the first dielectric block and separated from the resonator patterns; and a ground pattern connected to the ground electrode and disposed at least on one side of the first dielectric block and separated from the resonator patterns and the input/output pattern; and a second electrode pattern disposed on the upper side of the first dielectric block and separated from the first electrode pattern by a dielectric material constituting the second dielectric block.
