A shaped beam base station antenna is realized with the unequal spacing array using an optimization technique based on genetic algorithms.Antenna model have been evaluated by using the Method of Moment (MoM).During the antenna optimization process
an appropriate fitness function is used to suppress the sidelobe in interference zone
fill the null points in service zone and control the back lobe
to get satisfactory pattern shape in the whole frequency band.As a result of this optimization
a practical shaped beam antenna with suppressed sidelobe smaller than -18.32dB and backlobe -26dB
filled null point larger than -14.71dB was achieved.The proposed method is closer to reality compared with previous methods and can be used to optimize complicated antennas.The result is very useful for engineering and theoretic analysis.
