Abstract

A novel multifunctional exponentially tapered slot (Vivaldi) antenna exhibiting tunable frequency-notched and tunable narrow-band operation is proposed in this article. Integration of multiple varactor-coupled split-ring resonators (VC-SRRs) into the feed region of the Vivaldi yields a wideband tunable frequency-notched response upon suitable tuning of the varactor diodes. Furthermore, the VC-SRR-loaded Vivaldi, when augmented with suitably located switches connecting the slot line, yields a tunable narrow-band performance over an octave bandwidth centered around 5.25 GHz. © 1990-2011 IEEE.
