Array antennas offer a wide range of opportunities in the variation of their directivity
patterns through amplitude and phase control. Peak side lobe levels may be reduced
via amplitude control or weighting across the array aperture. Several authors have
made significant contributions in detailing processes for synthesizing these aperture
amplitude distributions for the purpose of side lobe level control. One of the basic
trades-offs when implementing amplitude weighting functions is that a trade between
low side lobe levels and a loss in main beam directivity always results. In this paper
we are implemented and compare the Binomial array, Dolph-Tchebyscheff array and
Taylor-Line Source array antennas. Descriptions of the amplitude tapers and their
utility will be presented.
