Brainstroke Detection Using Flexible Antenna Based On RTV Silicone Rubber Substrate

As the rates of brain strokes and necessity of early detections continues to escalate, the need of new innovative solutions keeps on rising. This research paper proposes a new design for a wearable antenna designed on RTV silicone rubber substrate making it lightweight, low profile and highly flexible. A system of carefully designed slots have been made on the antenna patch as well as a truncated side profiles have been employed for increasing the electrical length of prototype thereby decreasing the dimensions. The final dimensions measure at 38 x 27x 1 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>. This system works in ISM band of 2.45 GHz covering a bandwidth covering from 2.36-2.58 GHz and another band ranging from 2.89-5.34 GHz. The proposed prototype offers radiation efficiency greater than 95% in the two operating bands. In this paper, we have made use of bistatic radar technique to detect the stroke in the seven-layer human head phantom model.
