Context
Typically composed of one or more radiating surfaces illuminated by one or more focal sources, transmitarrays (also called discrete lenses) are a recent cutting-edge antenna concept. They are realized typically using multilayer printed circuit technologies compatible with the integration of the active devices (diodes, MEMS, NEMS, semi-conductors, etc.). These devices can be used to control the electromagnetic field on the array aperture with excellent performance (bandwidth, cross-polarization level).

Description
The main scientific & technical objectives of this PhD thesis, available at the CEA-LETI, Antennas and Propagation Laboratory, Minatec Campus, 38000, Grenoble, France, are the following: first experimental demonstrations (1) of highly efficient (70%) and highly directive (gain > 43 dBi) flat antennas at 300 GHz, (2) of ultra-flat transmitarray antennas, and (3) of self-alignment techniques for highly-directive antenna beams.
