Mutual coupling compensation of array antenna pattern

In order to analyze the impedance characteristics intuitively, the array antenna is equivalent to a port network. Based on this model, the relation between mutual coupling and mutual impedance is obtained, and a way to modify pattern considering mutual coupling is introduced. In addition, multi-population genetic algorithm is applied to compensate pattern considering mutual coupling, so that the mutual coupling effect of antenna array can be eliminated. Finally, all these theoretic research results are proved by simulation.
