Optimal radiation pattern synthesis of mutually coupled antenna array using an efficient compensation method

An efficient compensation method is proposed for the reduction of mutual coupling among elements an antenna array using optimum current amplitude excitation weights. The performance degrades heavily due to coupling. effect can neither be eliminated nor ignored in context design. Several analytical and numerical techniques have been past few decades calculation effect. Here, compensated by reducing driving impedance each identical element adopting grey wolf optimization moth flame algorithms, respectively. sum impedances reduced efficiently adjusting feed amplitudes all individual elements. Compared existing known methods, less complex, cost-effective easy implement commercial industrial applications achieve better performance.
