Wide Band Communication Architectures: Ultra Wide Band Phased Arrays  vs. Fixed Beams- high frequency Lenses

Extreme requirements emerge in some particularly challenging communications scenarios such as those in large stadiums where thousands users can potentially aim at communicating simultaneously in a very compact spatial region.

This talk will discuss two types of completely different architectures that are being investigated and compared right now at TU Delft. The first one would operate an Ultra wide band phased array covering 2 to 8 GHz, while the second one will  operate an array of dielectric lenses operating around 140- GHz. A few of the main design trade offs will be discussed, and a view of the preliminary results that have been achieved will also be presented.
