Abstract
A bandpass filter (includes a dielectric substrate, a first strip line formed on the dielectric substrate, resonators coupled to the first strip line, and a second strip line formed on the dielectric substrate coupled to the resonators. The resonators include a plurality of inductor elements formed on the dielectric substrate and composed of rectangular conductors having a long side direction and a short side direction, and a capacitor element for coupling the plurality of inductor elements and include a series resonance circuit composed of the plurality of inductor elements and the capacitor element. The length in the long side direction of the inductor element is less than half wavelength of the electromagnetic wave transmitted by the filter.
