Innovative Approaches Based on a Reactive Sorting Algorithm for Sum and Difference Antenna Pattern Design

This work presents two new approaches for the design of sum and difference antenna array. The first approach considers a configuration of sub-arrays that minimizes a “residual error” functional, while the second one a configuration that minimizes a “gain sorting” functional. The obtained results show that by means of such methods difference pattern close to the optimal ones can be obtained with simpler feed networks. This is the author's version of the final version available at IEEE.
