摘要
本文提出了一种具有片上天线的新型高度小型化的双频射频识别(RFID)应答器(标签)。该标签的尺寸为1.32平方毫米,采用低成本的130纳米互补金属氧化物半导体工艺制造。双频RFID标签支持13.56MHz的EPC (electronic product code) gen2 high frequency(高频)标准和868MHz的EPC gen2 ultra high frequency(超高频)标准。定制的内置芯片天线包括两个相连的谐振线圈。该天线可以在HF和UHF频段与RFID阅读器进行电感耦合。最大标签读取范围在13.56MHz时为2.5mm,在868MHz时为4.4mm。这种有限的读取范围可以通过不同类型的增强天线进一步增加。
This paper presents a novel highly miniaturized dual band radio frequency identification (RFID) transponder (tag) with an on-chip antenna. The tag has a size of 1.32mm2 and was fabricated in a low cost 130nm complementary metal-oxidesemiconductor process. The dual band RFID tag supports the electronic product code (EPC) generation (gen) 2 high frequency (HF) standard at 13.56MHz and the EPC gen2 ultra high frequency (UHF) standard at 868MHz. The custom built onchip antenna comprises two connected resonanting coils. The antenna enables inductive coupling to an RFID reader in the HF and UHF bands. The maximum tag read range is 2.5mm at 13.56MHz and 4.4mm at 868MHz. This limited read range can be further increased by different types of booster antennas.
