Abstract

A Bracelet shaped wearable Dielectric Resonator Antenna (DRA) is designed and analyzed in this paper. The proposed DRA is made of Bakelite and is capable of operating efficiently in the vicinity of four different frequencies (5.9 GHz, 6.5 GHz 7.1 GHz, 7.6 GHz) in C Band. A performance characteristic of the Bracelet DRA is investigated with the help of a model of human wrist wearing the Bracelet DRA. The DRA worn on human wrist model gives directivity ranging from 7.4dBi to 8.3dBi at different operating frequencies. Radiation efficiency up to 82.1% at 5.9 GHz is obtained. Maximum Specific Absorption Rate (SAR) obtained is 1.15 W/Kg which is within the safe level of 1.6 W/kg set by the Federal Communications Commission (FCC), United States. Simulation of the designed DRA is done using CST Microwave Studio Software. Comparable or better performance characteristics of the proposed DRA is obtained than those of several C band wearable antenna structures reported in recent literature.
