Optimizing amorphous-shape microstrip antennas

The automatic design of microstrip antennas involves a series of continuous parameters to be optimized and multiple objectives to be simultaneously fulfilled. When the shape of the patch is admitted to be amorphous, discrete parameters are added to the optimization stage. Here, we are proposing a hybrid- coded genetic algorithm to implement the search engine. Due to the existence of several attributes of the antenna to be simultaneously optimized, and given that they keep intricate relations among each other, the design process incorporates a comparative analysis of the electromagnetic properties presented by the obtained theoretical configuration and the effective response produced by the corresponding physical prototype.
