- Abstract
- A compact dual-band antenna for smart wristbands was proposed. The proposed antenna consisted of a shorted hook-shaped radiating element and a rectangular ground plane. The antenna satisfied the -10 dB reflection coefficient bandwidth requirement in WLAN (2.45/5.8 GHz) bands both in free space and on the arm phantom. The gain of the proposed antenna was greater than 2 dBi at the center frequency of each operating band. To apply the proposed antenna to a practical smart wristband, a battery was considered in this letter. This antenna attained a multiband performance and size miniaturization compared with an existing antenna used for a commercially available smart wristband. In addition, the specific absorption rate (SAR) of the proposed antenna was analyzed. The experimental and simulated results of the proposed antenna were in good agreement.
