A microwave sensor is designed to operate at 2.4 GHz for measuring vital signs in human body. A double-layer patterned ground plane (GP) has been conceived to minimize the sensor size and experimentally verified. More than 360 MHz of 10 dB bandwidth and 2.28 dBi of gain over this band makes this sensor suitable for medical application. The simulated SAR value is found to be 0.5 W/kg for 30 mW of input power, which is much less than maximum limit 1.6 W/kg average over 1 g provided by FCC. © 2021, Springer Nature Singapore Pte Ltd.
