A Compact High Gain Millimeter Wave Circular Fractal Antenna Design for Next-Generation Wireless Communications

This paper proposes a Taconic-based 28.25GHz Circular Microstrip Patch Antenna designed and fabricated for high-frequency applications. An extensive comparison has been made between five materials such as Rogers, Taconic, FR4, Quartz, PTFE, and Rogers which can possibly be used in the design of 28GHz band antennas. Out of these materials, Taconic material came out to give better results. Due to the increasing demand for improved antenna performance, gain, and other linear characteristics, the microstrip antenna has been improved by the addition of fractals. Since it has a compact size (10mm x 10mm) and higher efficiency, it can be used for 5G applications.
