Abstract
In a noncontact self-injection-locked sensor, a self-injection-locked oscillating integrated antenna is designed to radiate a signal to a subject and be injection-locked by a reflect signal reflected from the subject. Owing to the reflect signal is phase-modulated by vital signs of the subject, a demodulator is provided to demodulate an injection-locked signal of the self-injection-locked oscillating integrated antenna to obtain a vital signal of the subject.
