Phase-Only Excited Random Antenna Arrays

Usually random arrays have uniform amplitudes along the aperture and only contemplate a linear phase shift between antenna elements. In this paper, we show, through some numerical results, that it is possible to obtain great flexibility on the radiation pattern by exploiting the potential of phase-only excited random arrays. Indeed, when the phase-tapering along the array aperture is nonlinear, it is possible to obtain radiation patterns with characteristics that can not be obtained with conventional equally-excited random arrays.
