Abstract

The paper reports design of a miniaturized asymmetric coplanar waveguide (CPW)-fed ultra-wideband (UWB) antenna. Miniaturization in antenna is done by using the modification technique in radiator and ground plane of conventional CPW feed. As compared to a conventional rectangular CPW-fed antenna, the proposed UWB antenna has achieved 72.57% miniaturization in active area and 13.49% improvement in impedance bandwidth. The antenna achieves 126.53% measured impedance bandwidth from 2.7 to 12 GHz for magnitude of S11 < −10 dB and is the smallest single-layer antenna to the best of our knowledge which covers entire ultra-wideband. The proposed antenna is uniplanar with overall size of 18 × 16 × 1.6 mm3 (0.16 λl × 0.14 λl × 0.015 λl) and is discussed in terms of impedance bandwidth, radiation patterns, peak gains, phase response and group delay.
