Abstract

To monitoring the enlargement of lateral ventricle and brain atrophy by using a wearable non-invasive antenna .the most common form of neurode generation disease is Alzheimer's disease and leading cause of dementia today. The progressive shrinkage of the brain volume and weight is the effect of Alzheimer's disease. Currently, MRI and CT scanners can detect and show images of the brain during different stages of Alzheimer's disease. However, its limited accessibility, high costs, and static structure make it inconvenient for some to use. This paper presents a wearable device comprising of flexible microwave antennas, with an operating frequency range of 300 MHz to 3 GHz that detects the progression of brain atrophy and lateral ventricle enlargement in patients with Alzheimer's at the earliest stage possible. In this work, the software used to analyse and design the proposed antenna is CST studio suite. The operating principle of the antennas are simulated in near field using CST and the device is experimentally validated using lamb brain samples and samples representing cerebral spinal fluid (CST). The measured reflection coefficients (s11) were found to correlate with changes in brain volume and changes in volume successfully, thus giving an indication of the progression of Alzheimer's disease in a patient.
