摘要：
The design and realization of a ten-element shaped-beam antenna array are presented. A flat-top pattern in the main beam which allows a well-proportioned power distribution in desired zone is achieved by optimizing the amplitudes and phases of array elements using genetic algorithm. Being different from the most optimization in reported literatures, the proposed synthesis has taken the actual element patterns but identical and isotropic ones into account, which can reduce the error between computation and realization. Besides, both the optimized amplitudes and phases are set to be realizable. The array operating at 1.71-1.74 GHz is manufactured and measured. The measured radiation patterns of the proposed array show a flattop main beam of about 40. and a peak side-lobe level of -20 dB, exhibiting a good agreement with the simulated results.
