Abstract
A phased array antenna system comprises a feeding network which includes power combiners/dividers and an amplitude tapering system. The phased array antenna system comprises a plurality of antenna elements coupled to the feeding network. The amplitude tapering system is configured to generate amplitude coefficients and apply an amplitude tapering function on a transmitted or received radio frequency signal. The amplitude tapering function comprises a combination of a least two disparate amplitude tapering functions.
