A wireless vital signal detection system, which is analogous to Doppler radar, can measure respiration and heart rates with periodic movement of skin and muscle near the heart. The detection system consists of antenna, RF transceiver (transmitter and receiver), and baseband section. In this paper, the link budget of the detecting system is analyzed and the signal detected from the system is compared with the electrocardiogram (ECG) signal of a monitor which is used for patient monitoring in a hospital. Then, the detection of vital signs is also performed according to various environments, such as different distances and behind a wall.
