Abstract
A patch antenna array has been presented at 10GHz frequency with improved gain (14dBi) and far-field radiation capabilities for accurate detection of human respiration and heart beat rate with Doppler radar technique. The measured and simulation antennas’ results showed good agreement. Feasibility of 10GHz channel has been studied for remote vital sign monitoring (RVSM) under Doppler radar theory. Both the breathing rate (BR) and heart rate (HR) of a man have been accurately detected from various distances ranging from 5cm to 4m with as small transmitted power as −10dBM.
