Abstract

In this paper, an inverted Ω-shaped antenna is designed and presented for 2.45 GHz ISM band wearable applications. The proposed antenna is designed using Rogers’s 3006 material with thickness of 1.27 mm as substrate. Antenna radiating element is designed by using inverted Ω shape connected to a fork-shaped stub. This microstrip fed antenna maintained a partial ground at back side. The wearable antenna is simulated under different conditions, and the comparative analysis is presented for flat and bended positions in off-body and on-body conditions. The simulation analysis showed that the antenna operates at 2.45 GHz with band width around 260 MHz. At 10 mW input power, the proposed antenna exhibited specific absorption rate (SAR) value at 0.45 and 0.53 W/Kg for flat and bended conditions, when positioned on left arm phantom model. The simulated and measured reflection coefficient data comparison for off- and on-body conditions showed good agreement.
