Multi-human-body vital sign ultra-wideband radar monitor based on eye-shaped differential antenna

The invention discloses a multi-human-body vital sign ultra-wideband radar monitor based on an eye-shaped differential antenna. The ultra-wideband radar monitor comprises an XETHRU X4 ultra-wideband radar chip, an ultra-wideband differential transmitting antenna, an ultra-wideband differential receiving antenna and a microprocessor with a QSPI interface, wherein the XETHRU X4 ultra-wideband radarchip is located on the front face of a multilayer PCB, and the ultra-wideband differential transmitting antenna and the ultra-wideband differential receiving antenna are printed on the same multilayerPCB plane and located on the left side and the right side of the XETHRU X4 ultra-wideband radar chip respectively. The beneficial effects are that the radar monitor is high in detection sensitivity,is high in anti-interference performance, and can distinguish the vital signs of multiple target human bodies. 本发明公开了一种基于眼形差分天线的多人体生命体征超宽带雷达监控仪，包括XETHRU X4超宽带雷达芯片、超宽带差分发射天线、超宽带差分接收天线以及带QSPI接口的微处理器，所述XETHRU X4超宽带雷达芯片位于多层PCB电路板正面
