Design and evaluation of flexible CPW-fed Ultra Wideband (UWB) textile antennas

Two new antenna designs for Ultra Wideband (UWB) applications are proposed and discussed. The structures feature a rectangular radiator with circular or rectangular slots. A co-planar waveguide (CPW) feed is utilized to feed power to both antenna topologies. The main aim of this work is to design, fabricate and evaluate the two antennas' performance, both in free space and on body. The analyses of the structures are carried out using CST Microwave Studio, before being fabricated using ShieldIt Super® conductive textile and felt substrates. A comprehensive dimensional analysis is presented before detailing out the experimental results in this work.
