Abstract: A dual band wearable antenna operating on 2.6 GHz (2570-2620 MHz FDD/TDD) and 5.2 GHz (802.11a) bands for Body Area Network (BAN) application is presented. The stack substrates of Felt and ethylene-vinyl acetate (EVA) foam are used to make the structure flexible. Maximum gain of 2.75 and front to back ratio of 8.35 is achieved on industrial scientific and medical (ISM) band. Additional bandwidth enhancement has been achieved by creating slots on partial ground plane. The calculated specific absorption rate (SAR) value is 1.33 W/kg for 1 g of body tissue. Simulated and measured results are presented for the proposed structure.
