This paper presents some recent advances in the synthesis of time-modulated arrays (TMA), focusing on the suitable optimization of the pulse sequences controlling the element excitations of the array for achieving constant instantaneous directivity.

Abstract
This paper presents some recent advances in the synthesis of time-modulated arrays (TMA), focusing on the suitable optimization of the pulse sequences controlling the element excitations of the array for achieving constant instantaneous directivity. In particular, the synthesis of time- modulated linear arrays (TMLAs) taking into account the nonideal switches behavior and the electromagnetic coupling phenomena between real elements have been proposed as well as a study of the constant-directivity TMLAs used for enabling directional modulation for physical layer secure communications, by exploiting the replicas of the signal generated in the sideband radiation.File | Dimensione | Formato | |
