We have proposed a UHF/HF multi-band RFID reader, and we have implemented it into SiP with Package-on-Package technology. The proposed SiP RFID reader has been designed to support both for EPCgloabal Class1 Generation 2 protocol of UHF band, and 13.56 MHz RFID protocols of ISO14443 A/B type, and ISO15693 standards. The operating mode is controlled by embedded 32-bit RISC core, and the mode can be selected by users. The area of implemented SiP is 40 mm × 40 mm with 4 substrate layers. The implemented reader SiP operates at single supply voltage of 3.3V. The maximum current consumption is 210 mA. The measured operating distances are about 5cm for 13.56 MHz modes, and about 20 cm for UHF mode.
