The csc2 pattern of an equally-spaced linear array antenna with given amplitude excitation was synthesized. The phase distribution was derived by using the principles of stationary phase and sampling the results. Results of computations and experiments show that the maximum error of the synthesized pattern is about±3dB
and the level of sidelobe outside the region of beam-shaping is well below -15dB.An analysis also indicates that the csc2 pattern of planar phased arrays will become distorted in curls as it is scanned off from the broadside in azimuth.
