Abstract

An integrated circuit suitable for use as part of a tag in RFID technology is disclosed. The circuit has an antenna (515) and processing circuitry therefor, the antenna and circuitry being formed on separate layers (513,515) of the integrated circuit and discontinuous electrically connected guard rings (508) protecting layers of the integrated circuit in the IC-portion (501). The guard rings (508) can form an energy storage device which can improve the performance of the antenna.
