Title:
RESONATOR, RESONATOR ASSEMBLY AND FILTER
Document Type and Number:
WIPO Patent Application WO/2018/091539
Kind Code:
A9
Abstract:
A resonator (40) for a filter comprises a cavity (49) defined by first (41) and second (42) opposing conductive end walls and a conductive sidewall (43). A dielectric element (44) extends into the cavity from the first conductive end wall and a conductive element (48) extends into the cavity from the second conductive end wall. The free end of the conductive element is an open end thereof and the dielectric rod extends into the free end, forming a gap between the periphery of the dielectric element and the interior surface of the free end of the conductive element. For a given volume, the resonator has a lower resonant frequency compared to dielectric or dielectric combline resonators of the prior art, and a smaller volume for a given resonant frequency.
