A full-scale concept demonstrator for the scan loss mitigation via integrating subarrays in sparse, linear arrays is presented for the first time. The array uses technologically attractive cavity-backed, U-slot, patch antennas. An effective computational philosophy is proposed, validated and applied for a full electromagnetic characterisation of the resulting very large, non-uniform array. The computational results highlight impressive improvements when compared to the performance of sparse arrays comprising elementary radiators, exclusively. These results provide compelling arguments for the superiority of a physical concept demonstrator designed along these lines. |
