Synthesizing sectored antennas by the genetic algorithm

The genetic algorithm is used to synthesize the directional circular arc array as a sectored antenna. Based on the desired pattern and the topography of the antennas, the synthesis problem can be reformulated into an optimization problem and solved by the genetic algorithm. The genetic algorithm will always converge to global extreme instead of local extreme and achieves a good approximation to the desired pattern. Numerical results show that the synthesized sectored antenna is good and effective to combat the multipath fading.
