Compact microstrip dual-band pseudo-interdigital stepped impedance bandpass filters for wireless applications

摘要

In this paper, the authors present a compact microstrip dual-band pseudo-interdigital bandpass filter structure with lambda_g/4 stepped impedance resonators which can be used for development of dual-band filter with second passband centered at frequency from 2f₀ to 3f₀ .The proposed filter has advantages of simplicity and compactness.
