An Flexible Wearable Compact Metamaterial-loaded monopole Antenna for Wireless Body Area Network

In this feild, the challenge is to construct a flexible antenna with good performance in the wearable environment. In this research work, a novel metamaterial loaded antenna is proposed to work in the wireless body area network. By employing a split ring resonator in the ground plane, we are able to obtain reduced size. The size of antenna is 25 mm x 19 mm x 0.3 mm with polyamide substrate making the antenna flexible. The obtained directivity in dB is 3.0529, with a good impedance matching. The proposed antenna is tested on cotton cloth textile material. In addition to this, the obtained specific absorption rate is 0.9 W/kg that is within the permissibe limits. No major difference is seen between the simulated and measured return loss. The return loss is tested with N9926A FieldFox Handheld Microwave Analyzer, 14 GHz. The simulated and measured return loss have been found in good agreement.
