Abstract
Electrodes having slot patterns, electrodes having strip patterns, or dielectric strips, for example, form transmission lines and resonator patterns on the upper faces of dielectric substrates or conductive substrates, for example. Resonators formed by the resonator patterns are arranged at the ends of the transmission lines at the end portions of the substrates. A pair of the resonators are electromagnetically coupled to each other, whereby the corresponding transmission lines are also connected to each other.
