Abstract
- A dual-port annular antenna with polarization diversity is proposed for smartwatch application. A modified T-shape monopole is integrated with an annular ring antenna. The two antennas are fed by coplanar waveguide (CPW) line and slot line, respectively. Both the two ports cover 2.4 GHz WLAN bandwidth. Besides, the back shell of smartwatches and the human tissue model are considered. The numerical results show that the two ports has orthometric radiation patterns. The antenna is analyzed both in free space and on human body. The gain and radiation efficiency is higher than 1.1 dBi and 30 % in the on body scenario.
