Optimization of director antennas

The optimization of director antennas is considered in the rigorous electrodynamic formulation, and numerical results on such optimization are presented. A software package has been created which makes it possible to optimize (with acceptable machine time) the antenna geometry to achieve a maximum directive gain with a number of directors up to 20. An appropriate selection of vibrator lengths and distances between vibrators makes it possible to achieve a 1.5-2-fold increase in the directive gain as compared with existing director antennas for the same number of vibrators.
