【 摘 要 】

References(14)Cited-By(1)This paper describes the synthesis method of uniformly excited unequally spaced planar array with maximum beam collection efficiency (BCE, i.e., the ratio between the power radiated over a target region and the whole transmitted power) using Particle Swarm Optimization (PSO) algorithm. Based on this method, feeding network of the arrays becomes simple and compact and is easy to implement. And here the multiple optimization constrains include the number of elements, and the array aperture. Comparison of representative example is presented, and the results show that an enhancement of BCE and a depression of the sidelobe level outside of the receiving region (CSL) can be obtained through the proposed method.
