Abstract

A microwave network is described for use with identical transmit/receive modules such that amplitude-tapered aperture distributions are obtained with no loss. High-efficiency low-sidelobe patterns are calculated for the line source case with sidelobes as low as -27.5 dB. An optimum minimum-loss design is described for arbitrarily low sidelobes. The effects of errors on sidelobes are shown to be the same as in any array. The extension of the technique to the planar array case is presented.
