Automated dual band patch antenna design by a genetic algorithm based numerical code

In this contribution a new automated approach for dual-band patch antenna design is presented. Starting from a rectangular patch shape (mother structure), genetic algorithms (GA) are adopted to detect, among all the possible shapes (child structures) that can be obtained from the mother structure, the optimal patch shape matching some given requirements without having to examine the whole set of child shapes. In order to analyse the mother rectangular patch frequency behaviour, the method of moments (MoM) in the spatial domain is employed and, then, such an analysis is used for the GA research procedure. As an example of the code synthesis capabilities, the design of a dual band patch is finally presented.
