Dielectric resonator

Abstract

Abstract PURPOSE:To reduce the line length up to a coupling point and to attain the expansion of degree of freedom of various circuit design by providing the line part coupled with the center conductor with magnetic induction in a dielectric resonator comprising a circumferential wall conductive face and an edge wall conductive face formed on one edge wall. CONSTITUTION:An exfoliated part 12 formed by removing a conductive material at one face of circumferential wall conductive faces 4 having four faces and a strip line 13 is formed by surrounding three sides by the exfoliated parts. That is, the upper end is connected to the circumferential wall conductive face 4 in the conductive face, the lower end has a free end not connected via the exfoliated part 12 to the edge wall conductive face 5 and the strip line 13 having a distance by the exfoliated part 12 so as not to be connected to the circumferential conductive face 4 is formed to both sides and it is the line part 11 being subjected to M coupling to the center conductor 6. Thus, a 3rd signal terminal T3 is imagined to the free end of the line part 11 and the equivalent circuit is as shown in figure A. Thus, the magnetic coupling defined with the degree of coupling in response to the length/width of the strip line 13 with respect to the inductor of the parallel resonance circuit.
