....of any jamming or interfering signal [6] This amounts to change in overall pattern. Successful performance of a wireless system depends on the agility of the antenna to adapt to the environment or link topology. It has been shown that independent control of amplitude and phase excitation [7] [9] can help realizing antenna designs which have higher degrees of freedom in the signal, allowing generation of multiple beams [10] carrying variety 1 of information.

....or link topology. It has been shown that independent control of amplitude and phase excitation [7] 9] can help realizing antenna designs which have higher degrees of freedom in the signal, allowing generation of multiple beams [10] carrying variety 1 of information. One can conclude from [7] that independent control of complex excitation can provide better pattern topography. The purpose of this investigation is to analyze arrays which have narrow beamwidths and lower sidelobes. This feature is studied by examining the effects of amplitude and phase tapers across the array elements. ....
