Genetic reconfigurability of a multi-size pixelled antenna

A smart antenna system has been designed combining reconfigurable antenna concepts with genetic optimization algorithms. The employment of different sized patches in the antenna geometry has allowed the use of a simpler structure with a low number of switches while maintaining a good reconfiguration capability. The combination of the previous antenna with genetic synthesis algorithms have made up a smart antenna system capable of steering the radiation pattern over an angular sector of 120°. A simpler prototype has been manufactured and measured, presenting a good agreement with simulated results.
