This paper proposes a millimeter-wave (mmWave) radar sensor architecture for contactless vital signs detection and monitoring at the industrial, scientific, medical (ISM) 60 GHz band. Such fast remote touchless monitoring is extremely important during pandemic seasons such as COVID-19. The architecture utilizes a leaky wave antenna to synthesize a reconfigurable radar beam whose direction is steered in the space without additional modulator circuits. The modulatorless architecture enables monitoring the vital signs of multiple patients at different locations by measuring the Doppler shifts from their movements. Furthermore, it also offers building power and cost effective sensor components by eliminating the modulator circuitry. The system considerations of the proposed architecture are discussed and the Doppler radar technique for vital signs detection is reviewed. A laboratory experiment of measuring the Doppler shift due to a vibrating target using a prototype of the proposed sensor is successfully conducted. The application of the proposed sensor can be extended to remotely scan and control running machines in industrial environments.
