Abstract
An multiband resonator of the present invention includes a dielectric substrate including three or more dielectric layers, a ground conductor, a main-line conductor, a sub-line conductor, a sub open stub, a main open stub, a short-circuit conductor, a main through conductor, and a sub through conductor. The short-circuit conductor electrically connects one end of the main-line conductor to one end of the sub-line conductor and to the ground conductor. The main through conductor electrically connects the other end of the main-line conductor to one end of the main open stub that is aligned with that other end of the main-line conductor. The sub through conductor electrically connects the other end of the sub-line conductor to one end of the sub open stub that is aligned with that other end of the sub-line conductor.
