Abstract

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.
