Description

We present a study on the performance of wideband, wide scanning arrays, when the elements are fed with a set of amplitudes and phases aiming at generating multiple independent beams. The formation of multiple beams is relevant in modern wireless communication applications, when diverse data streams can be sent from a single transmitter to users located in different directions. Wideband wide-scan arrays are characterized by strong mutual coupling between antenna elements. The impact of such coupling on the capability to generate multiple beams is investigated. More specifically the active reflection coefficient of the elements and the total efficiency of the array are estimated for different beamforming configurations.
