| Abstract: | An analysis is made on far-field distributions of hexagonal planar array and Chaos Immune Algorithm（CIA） based on the chaos theory is introduced. According to requirements for the ultralow sidelobe of the hexagonal array,an optimization method for pattern optimization of array antennas based on CIA is proposed, and the ultralow sidelobe pattern of the hexagonal planar array is obtained. Simulation results show that CIA has good application potentials due to its faster convergence rate and higher searching efficiency. |
