摘要：
This paper proposes a 3D printed lens antenna for contactless heartbeat and respiration detection using the millimeter-wave (mm-wave) radar to improve the signal-to-noise ratio (SNR). The proposed device consists of an mm-wave radar and a 3D printed lens antenna. A 60 GHz pulsed coherent radar is integrated with the sensor module to receive reflected signals. A customized 3D printed lens is utilized to improve the directivity of radar radiation. In experiments, the proposed device can improve the SNR of the heartbeat and respiration and improve the accuracy of detected heartbeat and respiratory signals. The results prove the feasibility of the proposed solution in improving SNR for contactless heartbeat and respiration detection.
