Abstract
An RFID chip package includes an RFID chip including a voltage booster circuit and processing an RF signal in a UHF band and a power supply circuit connected to the RFID chip and including at least one inductance element. A reactance component of an input/output impedance at an antenna-connecting input/output terminal of the power supply circuit is substantially 0Ω.
