A DIELECTRIC WAVEGUIDE FILTER

摘要

PURPOSE: A dielectric waveguide filter is provided to secure a high attenuation property at a desired frequency band by connecting desired resonators through an inductor. CONSTITUTION: A dielectric waveguide filter includes a body(210), a connecting part(220), and a substrate(230). The body comprises a plurality of resonators(211~216). A plurality of vertical grooves is formed in both sides of the body. A conductive material is coated on four surfaces of the body except for both surfaces. The connecting part electrically connects two or more resonators among the resonators, and is a variable notch cable. The substrate is connected to the body, and includes an input/output terminal.
