In order to use a patch array antenna in various telecommunications applications, its miniaturization and high gain are very important parameters. The antenna miniaturization allows its integration in small embedded systems and its gain allows increasing its range. Several techniques are used to achieve this goal. Our work aims to miniaturize and improve the performance of a circular patch array antenna through the combination of two techniques: the use of Defected Ground Structure (DGS) technology using the KOCH Snowflake Fractal structures. All simulations were performed by CADFEKO a Method of Moments (MoM) based solver.
