Multiple split-ring resonators for tri-band filter with asymmetric response
(Scopus, 2011)
A triple-band filter composed of multiple split ring resonators is presented. This filter is based on a chain of triple split ring resonators that produces three pass-bands. The change in the dimensions of the corresponding ...
