提出了一种应用于无线电能传输技术的新型射频识别系统的双频圆极化天线。虽然所提出的天线是一个薄的轻型圆形微带贴片天线与一个端口，它辐射宽波束CP波在两个RFID频段，920 MHz和2.45 GHz。因此，该天线不仅可以应用于双频RFID系统，而且可以应用于由WPT能量启动的新RFID系统。
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.
