The circular patch microstrip antenna is a device that supports 5G technology because it has a low profile and small dimensions. The circular patch antenna generally constructs of 3 layers of an electromagnetic material. The materials are a good conductor as the radiator and the ground plane and a natural dielectric as the substrate. Along with telecommunication developments, research in the field of antennas is significantly growing. The characteristics of the antennas must be adaptive to these telecommunication developments. One of the antenna research as the solution is an introduction to artificial electromagnetic material. Artificial dielectric is one of the artificial electromagnetic materials. As we have known, a single circular patch antenna has a narrow bandwidth (less than 5% of the center frequency) and a low return loss. This paper proposes an open-ring artificial dielectric. The proposed artificial dielectric is used to improve the bandwidth and the return loss. Furthermore, the circular patch antenna with and without the open-ring dielectric is proposed and conventional. The result shows that the proposed antenna has a wider bandwidth, 8.94%, a higher gain, 0.78 %, and a higher return loss at the center frequency, 5.25% higher than the conventional antenna. From these results, the open-ring artificial dielectric can improve the characteristics of the conventional antenna.
