  • Patent number: 6225946
    Abstract: Mutual coupling between radiative elements (210, FIG. 2) in a phased array antenna (110, FIG. 1) is employed to extend the effective aperture dimension of a radiative element. Mutual coupling is used to force selected modal resonances to occur in the radiative elements (210). The forced modal resonances create zeroes of transmission which are employed to improve the roll-off characteristics of the radiative element's radiation pattern.
