The design of wearable fractal antenna on the spiral shaped Metamaterial (MTM) substrate suitable for
Industrial, Scientific and Medical (ISM) (2.4-2.45GHz) frequency bands is presented in this paper. To reduce the SAR
value a spiral metamaterial meander is introduced in the ground plane. High-Frequency Structure Simulator (HFSS)
software was used to design the antenna. Maximum allowedSpecific Absorption Rate (SAR) value is 1.6 W/Kg which
indicates that the wearable antennas are safe for human. Jeans substrate is used to design the antenna. The reflection
coefficient of the antenna is -27 dB and the Voltage Standing Wave Ratio (VSWR) of the antenna is 1.05. The SAR
value of the proposed antenna when placed on Phantom neck is 0.78 W/Kg, which makes it suitable for wearable
applications.
