Dual-band E-shaped patch wearable textile antenna

Future utilization of smart clothing will necessitate applications of multi-function and multi-frequency wearable antennas. The paper addresses the development of a dual-band E-shaped textile antenna for wearable applications. We have considered felt fabric to design an antenna for 2.2 GHz and 3.0 GHz frequencies. The antenna input matching and radiation characteristics have been determined by FDTD simulations and by measurements. Numerical modeling of specific absorption rate was also performed. The results show clearly that E-shaped textile antennas are suitable for multiband operation.
