Abstract

This paper presents a novel approach for designing miniaturized distributed lowpass filters. We propose to utilize microstrip transmission lines based on multilayer substrates which support slow-electromagnetic propagation. Based on such substrates, very compact LPFs are presented with cut-off frequencies in the low GHz region, with the measured insertion loss varying from 0.5-1.7 dB and with a return loss better than 7 dB from 100 MHz-2 GHz.
