Radiation pattern synthesis of TMCAA using bacteria foraging optimization

In this paper radiation pattern synthesis of time modulated circular antenna array is dealt with. Optimal switching time sequence and optimal uniform inter element spacing is used as variable to control the radiation pattern of the array. The optimal value of controlled parameter can be obtained by the evolutionary optimization technique. Three algorithms real coded algorithm (RGA), particle swarm optimization (PSO), and bacteria foraging optimization (BFO) has been used and compared with their performance. The numerical results have been carried out by taking three array set of 12-, 18-, and 25-elements. Simulation results show better side lobe performance with respect to the uniform circular antenna array.
