Abstract – The design and simulation of a rectangular micro strip patch antenna including a rectangular slot defective ground (DGS) structure are the subjects of this study.  The antenna designed for center frequency of 2.4 GHz and is simulated utilizing HFSS software. The aim of the study is to evaluate the influence of the faulty ground structure on the performance of the antenna by varying the position of the rectangular slot. Performance parameters such as return loss, bandwidth, VSWR and gain are carefully evaluated to measure the effectiveness of the DGS structure. By systematically adjusting the of rectangular slot position, the antenna’s working performance under different configurations is thoroughly investigated. The results show significant improvements in antenna performance after introducing the rectangular slot defect. Notably, the operating bandwidth of the rectangular microstrip antenna experiences a significant increase from 60 MHz to 298 MHz, highlighting the effectiveness of the DGS structure. The comprehensive simulation and analysis of this study provides valuable insights into the optimization of microstrip patch antennas and paves the way for the creation of high-performing antennas that satisfy contemporary communication systems' required specifications.
