As a practical part, an array of parallel dipoles is designed to account for the mutual coupling effects on the performance of the array in terms of directivity, sidelobe level and null placement. Illustrative examples are considered to impose single or multiple nulls in the antenna pattern at specific interference directions with the maximum side lobe level reduction of array antenna designenTaguchi methodSidelobe LevelOptimizationMutual CouplingAntenna ArraysArticle
