Optimal Synthesis of Linear Antenna Array with wide Null Symmetry Using Novel Particle Swarm Optimization Technique

Imposing nulls in the radiation pattern of a symmetric linear array antenna with constant phase and excitation current but different in spacing between the elements is dealt in this paper. This idea can be achieved using NPSO technique. For comparing the results, PSOCFA is also considered. Consequences of using this technique are that the symmetric single and wide null is achieved in particular direction with optimal normalized varying spacing between the elements.
