Abstract : The millimetre-wave band (30-GHz – 300GHz) is about ten times broader than the centimetre wave one (3-GHz – 30-GHz). This large available bandwidth is thus favourable for many high data rate or high resolution communication and radar systems like broadband high data-rate indoor (smart home, gigabit offices) and outdoor wireless communication systems, wireless personal area networks in the 60-GHz band, radio over fibre systems, intelligent transport systems, and passive or active imaging / sensing, security and surveillance systems.
Due to this very wide diversity of applications, many different kinds of mm-wave passive, active and integrated antenna modules and systems (e.g. systems on chip, systems in package) have been introduced over the last decade together with the development of new micro-technologies (e.g. MEMS).
During the presentation, we will review some recent achievements on passive and reconfigurable planar / volumetric integrated antennas and systems at millimetre waves, with emphasis for operating frequencies below 100 GHz. A particular attention will be paid to several emerging applications (short range communications and Body Area Networks in the 60-GHz band, SatCom on the move in Ka-band, short range and long range automotive radars in the 77/79 GHz band).
