Modern day impulse-based systems, radar imaging, surveillance systems, internet of things (IoT) and on body sensors find Ultra-Wide Band (UWB) planar antennas as a suitable device to operate at low power and low interference metrics with larger bandwidth, ease of fabrication, and low cost. In this paper a compact planar Coplanar Waveguide (CPW) fed antenna for Ultra-Wideband applications is proposed. The antenna features tapered slots of different shapes making the structure an asymmetrical co-planar waveguide. The antenna was designed and simulated using Matlab. The coplanar antenna is mounted on Rogers RO 3202 substrate. The antenna yields an ultra-wide bandwidth of 11.279 GHz with 10 dB return loss from 2.3617 to 13.641 GHz. The antenna provides acceptable radiation patterns and Voltage Standing Wave Ratio (VSWR) less than 2 dB in the range of 2.28 to 12.769 GHz. © 2018 IEEE.
