ABSTRACT

This study investigates the effect of mutual coupling between array elements on the performance of a dipole-based plane wave generator (PWG). An expression for the coupling matrix of the PWG arrays is derived and utilized to calculate the radiation field, mitigating the degradation of quiet zone (QZ) performance caused by mutual coupling. By combining accurate field distribution calculations with a hybrid approach that integrates the least square method and genetic algorithm (GA), an efficient synthesis technique considering mutual coupling for PWG is developed to generate quasi-plane waves within the QZ. The amplitude-phase distribution and variations in QZ are analyzed for an 8 × 8 half-wave dipole planar array PWG, considering both with and without mutual coupling effects. Simulation results demonstrate our proposed strategy's robustness and high efficiency for synthesizing dipole-based PWG with strong coupling.
