Abstract
A band pass filter which is configured by a microstrip line, or a strip line is provided. The band pass filter has a first half wavelength resonator which resonates at a center frequency of a pass band, a second half wavelength resonator which resonates at the center frequency of the pass band, and a transmission line through which the first half wavelength resonator is wire-coupled to the second half wavelength resonator. A strong coupling can be stably realized without causing deviation of the resonance frequencies of resonators.
