Here, Ntot is the total number of unknowns. Numerical results for both printed and free-standing dipole arrays are presented to validate the algorithm's efficiency and accuracy.EnglishDiscrete Fourier transformIterative solversMethod of momentsPhased arrayAlgorithmsComputational complexityConvergence of numerical methodsDipole antennasDiscrete Fourier transformsElectric current distributionElectromagnetic wave scatteringIterative methodsMethod of momentsPermittivityBiconjugate gradient stabilized methodDipole arraysPeriodic arraysAntenna phased arraysArticle10.1002/mop.11136
