Space Fed Arrays for Overlapping Feed Apertures

An overlapping feed concept for a multiple feed per beam (MFB) antenna architecture is considered. As a first realization a space fed array configuration is focused within this paper. A demonstrator model consisting of a primary and a secondary antenna array was manufactured. The measurement results are in good agreement with the simulation results. Although, the characteristics of the farfield pattern are less appropriate for the required performance. Alternative solutions will be investigated in the future.
