Electromagnetic Bandgap Materials are artificially engineered materials exhibiting novel properties. Since their discovery and first demonstration in the late 1980's, interest in EBGs has grown explosively. The potential takeup of these structures in Communications and Sensing Systems is primarily due to the control of the frequencies and wavenumbers of propagating and non-propagating electromagnetic waves to an extent that was not previously possible. Much effort is now being concentrated on the design and manufacture of these different classes of EBG-based components. This presentation will highlight application areas of EBG technology at microwave and (sub) millimetre wave. It sets out with a brief introduction of the concepts. It then discusses some generic configurations and resulting practical applications. Examples of FSS, EBG and AMC generic technology in the microwave region include:
patch antennas, cavity antennas, parabolic antennas, metallo-dielectric antennas, waveguides, filters and tunable structures. Examples of applications are array antennas, high precision GPS, mobile telephony, wearable antennas and diplexing antennas. In the submillimetre wave region a 500 GHz dipole configuration is shown and some components.

Peter de Maagt was born in Pauluspolder, The Netherlands, in 1964. He received the M.Sc. and Ph.D. degrees from Eindhoven University of Technology, Eindhoven, The Netherlands, in 1988 and 1992, respectively, both in electrical engineering. In the period 1992/1993 he was station manager and scientist for an INTELSAT propagation project in Surabaya, Indonesia. He is currently with the European Space Research and Technology Centre (ESTEC), European Space Agency, Noordwijk, The Netherlands. His research interests are in the are of millimetre and submillimeter-wave reflector and planar integrated antennas, quasioptics, electromagnetic bandgap antennas, and millimetre- and submillimetre-wave components. Dr. de Maagt was co-recipient of the H.A. Wheeler Award of the IEEE Antennas and Propagation Society for the best applications paper of 2001. He was granted a European Space Agency Award for innovation in 2002. He was co-recipient of the LAPC 2006 best paper award. Dr. de Maagt serves as an Associate Editor for the IEEE Transaction on Antennas and Propagation.
