Detection of Brain Stroke Using Microstrip Slot Antenna
Authors: , ,
Abstract: Stroke is one of the world’s most serious health issue. A decrease of blood flow to a portion of the brain that results in brain tissue damage is termed as stroke in medical science. Blood clots and ruptured blood arteries in the brain are the main causes of strokes. A brain stroke can be categorized under ischemic stroke and hemorrhagic stroke. Existing approaches are noninvasive, but they are constrained by cost and reliability concerns. These diagnostic approaches are insufficient to detect stroke in human head. Hence, a microstrip slot antenna has been designed with stroke model and human head phantom model, and stroke is detected with the help of antenna. In 2.45GHz ISM band frequency range proposed antenna with circular edge slots and circular slot in the front plane and ground slotted plane has been designed. A 3-D seven layer simulated head phantom model is designed and interfaced with the proposed antenna with and without stroke model. The stroke is detected by observing changes in antenna performance parameters viz. return loss, peak gain, radiation efficiency. Sphere shaped stroke is detected by observing variation in the antenna performance parameter. The stroke detection is applied on the cylindrical phantom on the HFSS software. The result shows that the change in performance is experienced as the distance between the antenna and the head phantom changed. The value of peak gain and radiation efficiency decreases thus depicting the presence of stroke.
