Abstract
There is a lot of research being done on ultra-wideband antennas with band-rejection characteristics; such antennas are used in applications such as the internet of things and indoor tracking and localization. This paper presents a single-layer, Coplanar Waveguide (CPW)-fed, epsilon negative (ENG)-loaded UWB monopole with a single band-rejection characteristic. The proposed antenna comprises two unit-cells that are designed and loaded into an S-shaped monopole strip antenna, which forms an open-end ENG-TL monopole antenna. A 10-dB return loss characteristic (3.1–12 GHz) is achieved by merging five resonances: the Zeroth-Order Resonance (ZOR), the First-Positive-Order Resonance (FPOR) of ENG-Transmission Line (TL), open-slot modes (λ⁄4, 3λ⁄4) and 5λ⁄4 mode of a shorted monopole. A single-band notch characteristic is achieved between 3.4 and 3.8 GHz by deploying two pairs of radiating structures (two opposite open slots and two opposite L-shaped radiating strips). Opposing currents are excited in each pair, and therefore the total radiated field is cancelled at 3.5 GHz notched band. The proposed antenna is printed on a 1.6 mm thick FR4, single-sided copper substrate of dimensions 16 × 20 mm2. The fabricated prototype is tested, and both simulated and measured results showed that the proposed antenna represents a worthy state-of-the-art UWB antenna.
