<p>A plurality of dielectric resonators (2) are arrange in one row and each dielectric resonator is provided with a ground electrode (8) formed on the surface of a dielectric block. The dielectric resonator (2) at each end is provided with an I/O electrode constituting part (6) formed at a position on the face extending along the arranging direction of resonators, i.e. the traveling direction of a signal. The I/O electrode constituting part (6) comprises an I/O electrode (5) extending in the mounting face while having a short circuit point (7) connected with the ground electrode on the mounting face (9) extending along the arranging direction of resonators, and a dielectric block exposing part (4) interposed between a part other than the short circuit point and the ground electrode thus exciting resonance modes IN a plurality of frequency bands. A part for coupling the adjacent dielectric resonators (2) is also provided.</p> |
