Title:
DIELECTRIC RESONATOR AND DIELECTRIC FILTER
Document Type and Number:
WIPO Patent Application WO/2017/221954
Kind Code:
A1
Abstract:
The present invention adjusts the resonance frequency without changing the exterior dimensions, while using TE mode resonance. A dielectric resonator (10) provided with a dielectric block (20), an external conductor (30), and wall surface conductors (41, 42). The dielectric block (20) has a cuboid shape having a first surface (201) and a second surface (202) facing each other. The dielectric block (20) has a through hole (21) extending from the first surface (201) to the second surface (202). The external conductor (30) is formed on the outer surface of the dielectric block (20). The wall surface conductors (41, 42) are formed on the wall surface of the through hole. The wall surface conductor (41) is shaped so as to include the first surface (201)-side end section of the through hole (21). The wall surface conductor (42) is shaped so as to include the second surface (202)-side end section of the through hole (21). The wall surface conductors (41, 42) are separated by a separation distance (H).
