Abstract
Traditional antenna design uses discrete steps manually to create and optimize the antenna structure. This approach costs both time and effort, especially when a complex antenna structure is on demand. The evolutionary algorithm emerges as a potential alternative method to formulate the antenna model as well as to optimize the structure so as to comply with the design requirements. In this paper, we propose a method for determining the surrogate model and dimensions of an ultra-wideband patch antenna using a differential evolution algorithm. This antenna is desired to work at the frequency range of 2.45GHz to 5.8GHz for WLAN applications. Through the evaluation of reflectivity and investigation of the algorithm,the surrogate model is obtained faster with optimized dimensions. The algorithm is investigated with different strategies to detect the best strategy when an object is a differential evolution applied.
