Blood pressure (BP) is a clear sign of hypertension, a condition that can be hazardous and even fatal. Regular blood pressure monitoring is therefore crucial, but many people dislike cuff-based devices, and they can only be used while at rest. To address this need, this paper investigates the use of micro strip patch antenna technology to obtain BP values through an innovative technique. The change of transmission coefficient EM waveforms emitted by the antennas will be analyzed and correlated with brachial artery thickness to radius ratios and hence, blood pressure assessment at different pressure points. The suggested morphology based on simulations and data algorithms performed at couple of instances of brachial artery diameters to mimic the condition of blood flow. A dedicated analysis software provided to calculate the systolic and diastolic pressure levels.
