A Flexible Multiband Antenna for Biomedical Telemetry

In this paper, a flexible and compact multiband wearable antenna with a simple and low-profile structure is proposed and investigated. It is able to operate over the frequency ranges from 0.824 GHz to 0.975 GHz and from 1.90 to GHz to 6 GHz, covering the most of identified frequency bands for biomedical applications. Moreover, the antenna demonstrates robust on-body performance and provides a suitable balance between small antenna size, high on-body radiation efficiency (between 5% and 11% for operating frequency bands), and a low value of the maximum 10 g specific absorption rate (0.47 W/kg) on a homogeneous semisolid phantom.
