Abstract

A double-band circularly polarized (CP) antenna for a novel radio-frequency identification (RFID) system using a wireless power transmission (WPT) technology is presented. Although the presented antenna is a thin lightweight circular microstrip patch antenna with one port, it radiates wide beam CP waves at two RFID frequency bands, 920 MHz and 2.45 GHz. Therefore, the antenna can be applied not only to a double-band RFID system but also a new RFID system being booted up by WPT energy.

带交叉槽的双频单馈圆极化微带贴片天线

提出了一种应用于无线电力传输(WPT)技术的新型射频识别系统的双频圆极化(CP)天线。虽然所提出的天线是一个薄而轻的圆形微带贴片天线，只有一个端口，但它在920 MHz和2.45 GHz两个RFID频段辐射宽波束CP波。因此，该天线不仅可以应用于双频RFID系统，还可以应用于由WPT能量启动的新型RFID系统。
