Abstract

PURPOSE:To make a filter small-size by covering the inside and outside circum- fenerence except the edge face of cylindrical dielectric resonators with conductors and providing a slit at the center of the outside circumference to make it a connection part. CONSTITUTION:Dielectric resonators are coaxially cylindrical, and inside face 22 and outside face 21 except the edge face are covered with conductors. They have the half length of a TEM-mode fundamental wave but indicate length different by dielectric constant. Then, they indicate the maximum magnetic field at the center in the longer direction and the maximum electric field on both edge faces. Consequently, since the magnetic field is leaked to the external if covering on the cylinder outside face at the center of the maximum magnetc fieldis is eliminated throughout the circumference, a small-size filter can be obtained by arranging slit parts 24 as connection parts.
