High-performance uniformly excited linear and planar arrays based on linear semiarrays composed of subarrays with different uniform spacings

This paper shows that linear arrays with the design described in the title can outperform both uniformly spaced arrays and nonuniformly spaced arrays designed by other published methods. The linear model can be extended to planar arrays in ways that achieve excellent antenna performance while preserving the efficiency of the optimization procedure used in the design process.
