Design and Analysis of a Compact Dual-Band Wearable Antenna for WBAN Applications

The design and analysis of a compact dual-band wearable antenna for WBAN applications is presented. The antenna was prototyped on a semi-flexible Rogers Duroid RO3003™ with compact dimensions of 41 × 44 mm2 which corresponds to 0.33 λ0 × 0.35 λ0, where λ0 is the free space wavelength at 2.4 GHz.
