Design of a Low Sidelobe Planar Array Antennas

In this paper, the effect of array aperture distribution errors is considered and discussed, and a low sidelobe planar array antennas is synthesized. Through theory analyzing and calculating, the low sidelobe design method is obtained, and the design criterion is given. Furthermore, the results that considered the effect of array aperture distribution errors are compared with the ideal results that obtained from the Taylor line source method. It is shown that the sidelobe levels (SLLs) are enhanced because of the effect of feed aperture distribution errors. Thus the design method has a better application.
