Abstract:
A transmission line type resonator has a low-loss characteristic and, in order to realize the low-loss characteristic, the transmission line type resonator includes a laminate body formed of a plurality of dielectric sheets, a transmission line of complex right hand left hand system disposed between the plurality of dielectric sheets, and an external connection terminal disposed at the end face of the transmission line type resonator and connected with the transmission line of complex right hand left hand system.
