Integrated antennas for wireless interconnect and electromagnetic interference

Wireless interconnections in integrated circuits are a new alternative for distribution of clock between functions or chips. We propose integrated antennas in technology CMOS 0.12 mum allowing to transmit signals on chip in the frequency band of 10 GHz to 40 GHz and millimetre-length distances. The electromagnetic interferencepsilas generated by the radiation of the antennas and the other interconnections are studied in order to evaluate the feasibility of this innovative solution. The first constructed prototypes allow a transmission of -17 dB a distance of 2.5 mm which corresponds to one of the best currently known transmission for integrated wireless interconnection.
