Abstract
A filter includes first and second line patterns each having a length substantially equal to ½ of the wavelength of a pass-band frequency, and a resonator that is interposed between the first and second line patterns and is coupled therewith so that the first and second line patterns have open stubs in which connection points between input/output terminals and the first and second line patterns appear to be short-circuited when viewed from ends of the first and second line patterns.
