Dielectric band pass filter having an evanescent waveguide |
摘要 |
A highly compact band pass filter that has excellent mechanical strength is disclosed. A band pass filter according to the present invention employs a dielectric block of substantially rectangular prismatic shape constituted of a first portion lying between a first cross-section of the dielectric block and a second cross-section of the dielectric block substantially parallel to the first cross-section and second and third portions divided by the first portion and metal plates formed on the surfaces of the dielectric block. The first portion of the dielectric block and the metal plates formed thereon are enabled to act as an evanescent waveguide. The second portion of the dielectric block and the metal plates formed thereon are enabled to act as a first resonator. The third portion of the dielectric block and the metal plates formed thereon are enabled to act as a second resonator. The metal plates include a capacitive stub formed on a first surface of the dielectric block which is substantially perpendicular to the cross-sections.
