<p>A coplanar band pass filter (10) having a centerline (15) formed of at least first and second serially arranged conducting segments (18, 19) which are separated by a gap (16). The centered segments are flanked by a resonator (30, 31) for coupling return current from the first and second segments. Conducting members (40, 41) that may include conductive strips or conductive planes (270) are respectively provided on opposing sides of the resonator and centerline. Band pass elements (50, 60) may be provided in the conductive strips or planes to reduce or eliminate spurious pass band frequencies.</p> |
