Abstract :
This paper presents a new research in the field of timed antenna arrays. The study proposes the synthesis of timed antenna array for arbitrary shaped beam energy patterns. The synthesis is formulated as an optimization of the true-time delays and amplitude coefficients in order to obtain a desired mask and low side lobes. The optimization is by using the well-known particle swarm optimization. The simulation results show the performance of timed antenna arrays to provide accurate arbitrary shaped beam energy patterns.
