Abstract
In this article, we present a new design concept for a multifunctional antenna providing single/dual frequency-notched ultrawideband (UWB) capability and its complementary multiple narrow-band functionality from a printed coplanar waveguide (CPW)-fed annular-ring monopole antenna (ARMA). We achieved the proposed multiple antenna configurations by loading square split-ring resonator (SRR) pairs of different dimensions beneath the substrate and above the superstrate, along with copper strips suitably positioned on the CPW feeding section of the antenna. The proposed antenna is compact, because of SRR loading in the substrate and superstrate, which provide seven different antenna functionalities/responses originating from a single radiating annular-ring monopole printed on a dielectric substrate.
