A Dual-band Monopole Antenna with EBG for Wearable Wireless Body Area Networks
Keywords:
Dual-band, EBG structure, low SAR value, wearable antennaAbstract
This paper proposes a dual-band wearable monopole antenna adopting an electromagnetic bandgap (EBG) structure, which operates at 2.45 and 5.8 GHz ISM bands and is suitable for wearable applications. Both the monopole antenna and the EBG structure are fabricated on an F4B semi-flexible substrate having a dielectric constant of 2.2. The EBG structure effectively isolates the human body from the radiation of the antenna and reduces the specific absorption rate (SAR) of it by more than 97.5%. This improves the antenna gain and the peak gain reaches 9.1 dBi at 5.8 GHz. The wearable performance of the antenna showed that it can sustain good performance even under realistic human body loading. Besides, the antenna has a small size, which makes it ideal for wearable applications.
