Original Abstract Submitted

A physiological information sensing device includes a signal generator, a transmitting antenna, first and second receiving antennas, a signal processing circuit and a computing element. The signal processing circuit includes a mixer, first and second band pass filters. The transmitting antenna transmits a microwave signal generated by the signal generator. The first receiving antenna and the second receiving antenna receive first and second reflected signals respectively. The mixer integrates the first and second reflected signals, and performs demodulation to generate a demodulated signal. The first band pass filter filters the demodulated signal based on a first frequency domain to generate a first filtered signal, and the first second pass filter filters the demodulated signal based on a second frequency domain to generate a second filtered signal. The computing element outputs a heart rate and a respiration rate according to the first and second filtered signals.
