Abstract

Abstract PURPOSE:To steepen an attenuation characteristic, by coupling two optional dielectric resonators among plura dielectric resonators. CONSTITUTION:Internal electric conductors 121-126 are arranged in a channel shape in a shielding case 11. Cylindrical dielectrics 131-136 are installed in the circumference of each internal electric conductor 121-126, and constitute the respective dielectric resonators together with the shielding case 11. Each dielectric resonator is coupled by an electric conductor piece 1612 through 1661 for forming an interstage coupling capacitor, also both resonators consisting of the internal electric conductor 121 and 126 are coupled in the electric field by a coupling capacity element 21, and both resonators consisting of the internal electric conductor 122 and 125 in the magnetic field by a coupling hole 22.
