        abstract = {As a result of 5G wireless communications systems, there is an increased scope for more demanding antenna designs. Examples of these demands include but are not limited to; larger bandwidth requirements, increased antenna gain, smaller form factors and operation within higher frequency bands (e.g., mm Wave). The 28 GHz frequency band has generated a lot of research interest due to its larger frequency spectrum and ability to transmit higher speed data. However, traditional microstrip patch antennas (MPA’s), have been used primarily due to their smaller size and ease of integration. However, MPAs have limitations operating in the range of 5G frequency bands due to their inherent lower performance characteristics, e.g., bandwidth and gain. This research will therefore examine the design of a compact, highly efficient, circular microstrip patch antenna with a Defected Ground Structure (DGS). The materials used to construct the antenna include Rogers RT5880LZ due to its low loss and ability to operate consistently at millimeter-wave frequencies. The antenna will have a circular patch shape in order to improve radiation stability. The feed will use a microstrip to achieve impedance matching. The addition of a DGS pattern on the ground plane provides the principal improvement to the antenna compared to previous designs. The DGS enhances the antenna’s radiation efficiency, return loss, and bandwidth by introducing additional inductive and capacitive effects into the ground current distribution on the antenna, which modifies how current flows. The DGS achieves this without increasing the physical size of the antenna. The antenna performance was parametrically optimized through a thorough analysis of key design parameters including patch radius, feed inset location, and DGS dimensional values, with simulated results showing the proposed design’s validity.},
