A compact dual-band semi-flexible antenna at 2.45 GHz and 5.8 GHz for wearable applications

In this work, a compact dual-band semi-flexible antenna operating at 2.45 GHz and 5.8 for the industrial, scientific medical (ISM) band is presented. The fabricated on substrate material, Rogers Duroid RO3003™ with low-profile feature dimensions of 30×38 mm2 which makes it good solution wearable applications. Bending investigation also performed over vacuum cylinder diameters are varied 50 mm, 80 mm 100 that represents average human arm’s diameter. bending shows reflection coefficients all almost similar imply will operate resonant frequencies, even in condition. simulated specific absorption rate (SAR) CST MWS® software obeys FCC ICNIRP guidelines 1 mW input power. SAR limits g tissue 0.271 W/kg (FCC standard: 1.6 W/kg) while 10 0.0551 (ICNIRP 2 W/kg. On other hand, computed 0.202 0.0532 g.
