本文介绍了一种基于天线的射频无线功率和数据传输系统，用于重症监护病房中使用电阻抗断层扫描(EIT)的新生儿肺功能无线监测。该双频系统由一个定向缝隙贴片发射天线和一个工作在2.51 GHz和5.1 GHz的缝隙柔性全向单极子天线组成。提出了一种针对每个天线的独特的开槽技术，以实现双频工作和每个天线的尺寸小型化。同时，采用了与寄生单元相结合的阵列技术来提高接收天线的增益，进而提高接收功率电平。对发射天线和接收天线进行了仿真和制作。根据FCC的安全规定，当接收器和发射器相距19厘米时，测量结果显示接收功率为20 mW。
This paper presents an antenna-based RF wireless power and data transfer system for wireless neonate lung function monitoring in an intensive care unit using electrical impedance tomography (EIT). The proposed dual-band system comprises a directional slotted patch transmit antenna and a slotted flexible omnidirectional monopole antenna operating at 2.51 GHz and 5.1 GHz. A slotting technique unique to each antenna is proposed to achieve dual-band operation and size miniaturization for each antenna. Also, the arraying technique combined with parasitic elements is employed to increase the receive antenna gain and in turn the received power level. Both transmit and receive antennas were simulated and fabricated. Following FCC safety regulations, measurements show 20 mW received power when the receiver and the transmitter are spaced 19 cm apart.
