Modeling of Compact, Broad-stopband Lowpass Filter using Modified Stepped Impedance Hairpin Resonators

Sayed Ashraf Mamun and Abdul Matin

Abstract—A compact elliptical function lowpass filter using modified stepped impedance hairpin resonators is proposed. The filter is analyzed from the equivalent lumped-element model using transmission line theory. The model is evaluated with EM simulation with good agreement. For single lowpass filter, the return loss is better than 13 dB from DC to 1.5 GHz where the insertion loss is less than 0.5 dB with considerable pass band ripple, ±0.3 dB. The rejection is greater than -15 dB from 2.0 GHz to 10 GHz. By cascading proposed lowpass filters with different length and width, more rejection in stopband, low insertion loss, broad stopband can be obtained to design an efficient filter for many wireless communication systems.

Index Terms—Low pass filter, micro strip, hairpin resonator,broad stopand
