Abstract
Design of a dual wide bandstop filter is proposed based on
Composite Right and Left-Handed Transmission-line (CRLHTL)
. Two stop bands with center frequencies of 8.3 GHz and
12.9 GHz are achieved with fractional bandwidths 57.8% and
32.5% respectively. Spiral interdigital capacitors and stub
inductors are employed to designed filter. The proposed
bandstop filter provides low passband insertion loss, better
attenuation in stopbands, and low cost. The total filter size is
about 7.8mm×15.1mm which is very compact compared to
other metamaterial and conventional microstrip filters. Filter
is also fabricated and measured to demonstrate the
performance matched with simulation results.
