Abstract :
A technique is presented for generation of efficient superdirective array functions, using a composite polynomial based on the Cheby¿shev polynomials. The generated radiation pattern has a narrow main beam with high radiation efficiency, indicative of an array function which is tolerant to elemental amplitude and phase errors.
