This post-doctoral offer is in support of our work program on the design of millimetre-wave antennas for high data rate communication systems in the 57-66 GHz frequency band. The realization of smart devices in this frequency band with a high level of integration and a low cost is a challenge accessible today thanks to the recent microelectronic technologies as well as other silicon technologies such as assembly, packaging or micromachining. Some applications in the consumer electronics domain are clearly identified and expected to result in product in a very short term.
After a series of project completed these last years on the design of single antennas built and validated on different technologies, such as silicon or ceramic, the future projects will focus on the demonstration of antenna arrays with electronic beamsteering for long range applications. Several demonstrators will be realized in collaboration with our partners developing the integrated circuits and fabrication/assembly technologies in order to obtain a fully functional system.

Invisibility cloaking, sub-wavelength, thin antenna substrates, absorbers, etc., metamaterial structures have open many perspectives, some of them seeming futuristic while other being very practical given the current ste of the art in the domains of materials, microtechnologies and integrated optics.
this post-doctoral work will focus on the study of high-impedance surfaces and the possibility of transposition of these designs between very different frequency bands (6 GHz, 60 GHz, 60 THz) corresponding to a wide range of technologies and applications.
After a thorough bibliographic study of the current state of the art, the developments will include the design of high-impedance surfaces at the three frequency bands cited above and an experimental demonstration at 6 GHz and possibly at 60 GHz.
