<p>Provided are a bandpass filter and a radio communication module and a radio communication device using the same. The bandpass filter includes: a first and a second grounding electrode arranged on the upper and the lower surface of a layered body (10); single resonance electrodes (30a, 30b, 30c, 30d) and composite resonance electrodes (29a, 29b) arranged to orthogonally intersect the single resonance electrodes (30a, 30b, 30c, 30d); a first input coupling electrode (40a) opposing to the single resonance electrode (30a) of the input stage and a second input coupling electrode (41a) connected thereto and opposing to the composite resonance electrode (29a) of the input stage; a first output coupling electrode (40b) opposing to the single resonance electrode (30b) of the output stage and a second output coupling electrode (41b) connected thereto and opposing to the composite resonance electrode (29b) of the output stage.</p> |
