Dielectric resonators have become very important thanks to the daily evolution of telecommunication systems which aim to continually reduce the size and the weight of systems, besides rising the frequency and the bandwidth. In this paper, a flexible antenna using dielectric resonator antenna is presented and designed using textile materials for wearable applications at the WLAN band. The designed antenna is meant to act like a button placed on the shoulders. A study on the antenna/body interaction beginning with a comparison of the performance of the free space antennas, as well as that of a phantom rectangle with the physical properties of the human body is verified. Next to that, an impressive gain of 5.4 dB is achieved at the operating frequency of 5.8 GHz. It has been confirmed that the specific absorption rate meets the standard. Another study on the influence of a mobile phone on the operation of the antenna has also been presented. These results were confirmed by the measurements.
