An Effective Optimization Algorithm for Synthesizing Wideband Thinned Array Antenna

This paper proposes an optimization algorithm for a sparse wideband planar antenna array based on the covariance matrix adaptive evolutionary strategy algorithm. By dividing the planar antenna array into multiple regions, the goal of achieving faster optimization results is achieved. When directly applying the covariance matrix adaptive evolutionary strategy algorithm to optimize a large number of antenna elements in an antenna array, the computer may run slowly or even fail to produce results. For a given antenna array aperture, before using the covariance matrix adaptive evolutionary strategy algorithm to optimize the antenna array, the array can be divided into several sub-arrays symmetrically, so that the running efficiency of the optimization algorithm will be greatly improved.
