Abstract
In this paper, a uniplanar tri-band antenna for smart watch applications is presented. Implemented on a FR4 substrate and occupying 38x38x0.8 mm(3), the antenna supports Bluetooth, WiFi 2.4/5.8 GHz and WiMAX 3.8 GHz bands. The antenna is composed of an edge tapered, bent monopole element with a capacitively coupled inverted L shorting strip supporting the tri-band operation in 31 VSWR standard and exhibiting positive gain in all bands. The specific absorption rate of the antenna is well within the acceptable limits specified by FCC.
