In this study, an innovative approach for the synthesis of time-modulated linear array (TMLA) antennas is presented. The switch-on instants of the time-modulated elements are taken into account as additional degrees of freedom to optimise the array pattern. Towards this end, a technique based on a particle swarm optimisation is proposed to fully exploit the dependence of the sideband radiations (SR) on the shift of the time pulses. A set of representative results are reported to assess the effectiveness of the proposed approach as well as its flexibility.

Abstract

In this study, an innovative approach for the synthesis of time-modulated linear array (TMLA) antennas is presented. The switch-on instants of the time-modulated elements are taken into account as additional degrees of freedom to optimise the array pattern. Towards this end, a technique based on a particle swarm optimisation is proposed to fully exploit the dependence of the sideband radiations (SR) on the shift of the time pulses. A set of representative results are reported to assess the effectiveness of the proposed approach as well as its flexibility.
