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. was prototyped on semi-flexible Rogers Duroid RO3003™ with dimensions 41 × 44 mm 2 which corresponds to 0.33 λ 0 0.35 , where the free space wavelength at 2.4 GHz. designed in preliminary stage resonate 5.8 An inverted U-shaped slot added patch create one more resonant frequency In order enhance antenna’s bandwidth gain, two slots patch’s bottom edge partial ground are added. measured percentage impedance GHz 3.75% 5.17%, respectively. gain be 3.74 dBi 5.13 efficiency 91.4% 92.3%, respectively operating bands. radiation patterns exhibit bidirectional directional pattern E -plane bands, while omnidirectional observed xmlns:xlink="http://www.w3.org/1999/xlink">H -plane. At GHz, SAR limits simulated 0.955 W/kg 0.571 1 g 10 human tissue, 0.478 0.127 W/kg, Therefore, proposed has met FCC ICNIRP standards. Bending conditions on-body measurements indicate that performance unaffected. As result, it shown possessed ability utilized applications.
