设计了一种适用于UHF频段可穿戴设备和RFID应用的新型印刷天线。天线设计是根据最近文献中的基于能量的设计准则进行的。通过将电能密度限制在远离天线边界的区域中来实现相对于人体耦合的高鲁棒性。所提出的配置还提供了紧凑的实现和高通用性，因为它可以很容易地匹配到不同的商业芯片。这种可穿戴天线的原型已经制造和测试在消声环境中。读取范围的实验测量证实了数值模拟的结果，并证明了天线的鲁棒性相对于体天线耦合的情况下的变化。
A novel printed antenna is designed for wearable and RFID applications in the UHF band. The antenna design is performed following energy-based design guidelines available in the recent literature. High robustness with respect to the human body coupling is achieved by confining the electric energy density in a region far from the antenna borders. The proposed configuration also provides a compact realization, and a high versatility, since it can be easily matched to different commercial chips. A prototype of this wearable antenna has been manufactured and tested in an anechoic environment. Experimental measurements of the read range confirm the results of the numerical simulations and demonstrate the antenna robustness with respect to the variations of the body–antenna coupling scenario.
