COMPACT MICROSTRIP STEPPED-IMPEDANCE HAIRPIN RESONATOR LOW-PASS FILTER WITH APERTURE

摘要

A new microstrip stepped-impedance hairpin resonator (SIR) low-pass filter (LPF) using aperture is proposed. This filter has the advantages of compact size and easy fabrication, Also, it provides a very sharp cutoff-frequency response with low insertion loss of 0,1.3 dB and wide-stopband characteristic. The filter is useful for many microwave-system applications.
