Band-pass filter for mobile communication system, has half wavelength microstrip resonators connected between ends of straight quarter wavelength microstrip conductors

摘要

Even numbered half wavelength microstrip resonators (L,H) with odd numbered straight and hairpin microstrip conductors, are connected sequentially to a neighboring resonator over a spacing. The microstrip resonators are connected between ends of straight quarter wavelength microstrip conductors (M) that are connected to a gap coupling circuit (C).
