Abstract :
A novel design concept for a versatile multi-functional coplanar waveguide (CPW)-fed ultrawideband (UWB) printed antenna is described in this letter. The antenna also exhibits a dual complementary characteristic of frequency notched response and narrowband response invoked by different combinative loading of a pair of split ring resonators (SRRs) and metallic shunt strips on the CPW feed line. The antenna restores its UWB response when the SRRs´ split gaps are shorted. The simulated impedance and radiation characteristics are validated with measured results obtained using fabricated prototypes to establish the proof of concept.
