Study of Designing BPF by Using LC Tap-Coupling Resonators
The resonance characteristics of short-ended half-wavelength coplanar waveguide(CPW) LC tap-coupling resonators are examined theoretically and experimentally. The characteristics near the passband have been improved by applying the presented CPW resonator to a design of a bandpass filter(BPF). Moreover, the difference between the calculation and the measurement results is examined by using the equivalent circuit about the presented BPF.
