A Miniaturized Implantable Antenna for Bio-Medical Applications

A miniaturized implantable antenna (MIA) is presented here by utilizing meander-lines and parasitic stub techniques. The miniaturized antenna has electrical dimensions of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$0.17 \lambda_{0} \times 0.17 \lambda_{0}$</tex>. The proposed MIA has a resonating frequency of 5.1 GHz which can be recommended in Biomedical applications. The MIA is designed with Rogers (RT) 3010 substrate (0.25 mm) to make it conformal. The phantom analysis is executed to validate the design performance inside the human body and obtain satisfactory results. The maximum SAR value while using the proposed MIA is observed <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1.51 ~\mathrm{W} / \text{kg}$</tex> which confirms the safer use of the antenna design as per the standard of IEEE.
