  • Abstract
    A cost function is given for the optimization of the directivity of an antenna array while simultaneously achieving the flat behavior over the wide range of frequencies. The optimization of a six-element Yagi antenna resulted in a virtually flat directivity over the bandwidth of 33 percent. The allowable tolerances on element lengths of the optimized antenna are 0.25 percent or larger.
