DIELECTRIC COAXIAL RESONATOR

PURPOSE:To easily perform frequency adjusting work for a dielectric coaxial resonator used in the oscillation circuit of a high frequency circuit. CONSTITUTION:This resonator is constituted of a cylindrical dielectric 11 provided with a through hole 13a almost in a center part, an external conductor 12 formed on the outer peripheral plane of the dielectric 11, an internal conductor 13 formed on the wall plane of the through hole 13a, and a connection terminal 17 to be inserted from a release end face 14b provided at the another terminal side of the dielectric 11 to the through hole 13b. The insertion part of the connection terminal 17 to the through hole 13a is formed in zigzag shape provided with plural projections by employing such constitution.
