A radio frequency identification reader antenna having multitag identification for medical systems is presented, which consists of four PIFAs, two hybrid couplers, and four power dividers. The high isolation is achieved by the symmetric design of the antenna geometry and four power dividers, which are fed by two hybrid couplers. The experimental results show an isolation of more than 40 dB in the North American (902–928 MHz), Korean (917–923.5 MHz), and Japanese (916.7–923.5 MHz) RFID frequency bands.

具有多标签识别功能的UHF RFID阅读器天线,用于极端低温医疗系统

提出了一种具有用于医疗系统的多标签识别的射频识别阅读器天线,该天线由四个PIFA,两个混合耦合器和四个功率分配器组成。高隔离度是通过天线几何形状和四个功率分配器的对称设计实现的,两个分配器由两个混合耦合器馈电。实验结果表明,在北美(902-928 MHz),韩国(917-923.5 MHz)和日本(916.7-923.5 MHz)RFID频段中,隔离度超过40 dB。
