Optimization of the end-fire beam pattern of two-dimensional dipole array

We have laid down the optimization guidelines for the scanning of the beam-pattern in the azimuth direction. The procedure of selecting the initial values by using the principle of reciprocity followed by the local optimization is more suited to this application as it gives an accurate value with less iteration. We also show that phase-only technique which is relatively easier to implement is applicable within the two ends of the scan range which provides almost the same quality of beam-pattern compared to the both phase and amplitude technique.
