Polarization-agile ADS-interleaved planar arrays
Résumé
This paper presents a class of polarization-agile arrays with controlled sidelobes. The architecture is based on the interleaving of two independently polarized sub-arrays through a deterministic strategy derived from Almost Difference Sets (ADSs). The efficiency, flexibility and reliability of the proposed design technique is assessed by means of a set of numerical simulations. Moreover, selected experiments aimed at comparing the performances of the presented approach with state-of-the-art design are provided. Finally, mutual coupling effects are numerically analyzed and discussed.
