This letter presents a tunable bandwidth bandpass
filter based on varactor-loaded metamaterial coplanar waveguide
(CPW) lines. The CPW lines are based on series gaps and
split-ring resonators. The varactors are reverse-biased semiconductor
diodes connected between both sides of each series gap.
This configuration, directly inspired from the so-called metamaterial
technology, takes advantage of the high dispersion of
the loaded transmission line. Therefore, strong permittivity and
permeability responses induced by means of the resonators are
obtained. A single varactor-loaded transmission line is first analyzed.
Then, a third-order tunable filter with fractional bandwidth
tuning range from 5.8% to 21.5% is experimentally assessed. The
proposed filters can be used in several practical applications such
as multichannel wireless and satellite communication systems,
where reconfigurable devices are often required.
