ABSTRACT
The Side Lobe Level (SLL) of the main beam ofa uniformly excited time modulated antenna array isreduced to less than -55 dB by using Genetic Algorithm(GA). For a uniformly excited linear antenna array themaximum side lobe level is ~ -13.5 DB. In this work theuniformly excited antenna array is first time modulatedand then the on-time sequences of each of the arrayelements are optimized by applying GA to get the desiredresult.
