The importance of wearable products such as wearable textile antenna is increasing day by day because of the recent miniaturization of wireless devices. In the last few years it has received a vast amount of attention due to utilization in smart clothing and future consumer-centric communication technologies. The main challenges for designing textile antennas are low weight, low profile and low cost. The fabrication technique and the use of materials are important factors which play an important role in the overall performance of the antenna. The permittivity and thickness of the substrates determine the efficiency and the bandwidth of a planar microstrip antenna. This paper investigates the effect of substrate thickness over bandwidth for different textile materials. Seven types of textile dielectric materials have been used for comparing the result for modified circular and ring-shaped microstrip patch antennas. The antennas are fed with transmission line feed. The simulated results showed that our designed antennas operate up to 20 GHz with miniature size and high gain. All the antennas are simulated in computer simulation technology (CST) studios.Keywords: Wearable antenna, textile substrate, quality factor, bandwidth, return lossCite this ArticleAparajita Biswal, Vishal Vora.
