To study and demonstrate by analysis a reflector antenna architecture able to generate several different beams from a shared shaped reflector aperture.

The activity focuses on the design of an antenna architecture featuring a single reflecting surface able to generate several different beams. Several feeds can be used to illuminate a shared shaped reflector with locally modified reflection characteristics so has to form separate beams. A dedicated design procedure is required to allow an efficient antenna performance optimisation, including an initial high-level synthesis of the antenna geometry and surface layout, followed by a full-wave optimisation of the reflecting surface. The activity encompasses two steps. The first step involves the definition of applications scenarii and requirements followed by the demonstration of feasibility by analysis. The design procedure will be then defined and implemented in parallel. As a second step, candidate solutions will be designed in detail for the most challenging scenario and their performance demonstrated by analysis, with validation on laboratory test pieces if necessary.
