Abstract
This article presents a conformal monopole antenna for wearable application in ISM band frequency of 2.45 GHz. The antenna has a return loss of 50.18 dB with good radiation performance. The gain of the antenna is 1.09 dBi which is improved to 3.28 dBi using a metasurface consisting of 3 × 3 array elements. The proposed metamaterial integrated antenna is fabricated on 1 mm thick flexible PDMS substrate. The metamaterial improves the gain while reducing the specific absorption rate (SAR) of the antenna. The geometry size of the metamaterial integrated antenna is 50 × 50 × 24 mm3. The loading effect of antenna by body is analyzed with a hand phantom model. Flexibility and conformability of antenna is analyzed by bending the antenna with various radii in x and y direction. Measured results of the fabricated prototype demonstrate the safety of the suggested wearable antenna for biomedical applications.
