Dipole Antenna Array Synthesis for the Improvement of the Performance Using FPA

In this paper, the authors present a strategy for the synthesis of linear array antennas for performance increase with minimum variation in active impedances by employing a meta-heuristic optimization process known as the flower pollination algorithm (FPA). This approach is utilized in conjunction with the development of a far-field pattern with a defined side lobe level (SLL), first null beam width (FNBW), and several single and one broad null placement. Taking the asymmetric excitation voltage amplitudes of the array element, the requisite outputs are obtained. The mutual coupling of parallel dipole antennas has been studied. In one example, thirty parallel dipole antennas are used to show the effectiveness of the proposed approach.
