The design and implementation of a non-contact RF (radio frequency) sensor that can monitor vital signsrespiration rate and heat rate is proposed. The designed low-cost system operates at 2.45 GHz by using one single Yagi antenna system to transmit and receive RF signals, realizes a miniaturized design of PCB that integrates both microwave transceivers and receivers. The gain of the sensor is 8.96...
In this article, a design of non-contact sensor which is based on PCB (Printed Circuit Board) antenna for monitoring physiological parameters is proposed. In order to remotely monitor the activities of heartbeat, respiration and body movement, this article designed and implemented a Yagi patch antenna whose working central frequency is 2.45 GHz. The gain of the original antenna is 8.1 dB. Considering...
