Sidelobe control of antenna patterns

Using the iterative sampling method, sidelobe peaks can be made to conform to a specified shape within a given tolerance. The iterative sampling method allows the specifications for a given problem to be just satisfied, thereby avoiding an overdesigned pattern which may have a complicated current distribution or wide main beam. The type of calculations involved are typically only summations of series of elementary functions and, consequently, the method is easy to apply to both large and small antennas. Several computer examples are presented, all of which have low ratios of maximum to minimum current amplitudes and low super directive ratios.
