Frequency selective surface antenna for remote vital sign monitoring with ultra-wide band doppler radar

Abstract

A high gain frequency selective surface (FSS) antenna is proposed for noncontact remote vital signs monitoring (RVSM) with low power (−10 dBm) Doppler radar at 9.9 GHz frequency. High antenna gain (18.25 dBi) and narrow beam‐width enhanced the accuracy of human breathing rate (BR) and heart beat rate (HR) detection from remote distance in the range of 5 cm to 1 m. Two antennas have been fabricated and tested for which the measured and simulation results showed good agreement. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:818–823, 2017
