These applications require the development of innovative antenna arrays with very large frequency range of operation and good scan performance over wide angular ranges. The wide bandwidth is crucial to cover multiple frequency bands concurrently in a single wideband shared aperture and thus to overcome the very limited space available to place the antenna systems. Moreover the generation of several simultaneous beams for establishing multiple connections at once with a single antenna is fundamental, but very challenging because of the interference between beams.
When the phased array has to fit on a small platform (e.g. on a smartphone), fundamental scientific challenges need to be solved: modelling of small antennas, analysis of edge effects, study of multi-beam interference, reduction of surface waves.
The goals of this research subgroup are:
1) solve the fundamental limits of phased arrays integrated on small platforms
2) improve the current state-of-the-art of the antenna systems
3) link the antenna development to parallel development in other fields: electronics, packaging, radars, beamforming.
