Abstract :
Worldwide, stroke is the leading cause of adult disability. Stroke occurs when the blood supply in a part of brain is disturbed as a blood vessel bursts or is blocked by a clot. Delayed or wrong medical analysis can be fatal for the stroke affected patient. In this paper, a compact antenna is proposed for the brain stroke detection system. The antenna provides 77% fractional bandwidth (centered at 2 GHz) with stable gain and high front to back ratio. A compact radar-based system is developed using the proposed antenna for stroke detection. To test the system, a hemorrhagic stroke-affected human head is constructed emulating the actual electrical properties of human tissues. The image received by the post-processing algorithm explicitly detects and locates the position of the stroke.
