Gazi University Researchers Develop Novel Pixel Antenna for Wi-Fi 6E Applications

Strategic Insights -

Researchers from Gazi University, led by Kayhan Celik, have developed a novel pixel patch antenna optimized by a metaheuristic optimization algorithm for Wi-Fi 6E applications. The antenna is designed to operate in the 5.75-8.46 GHz frequency band and has a compact volume of 25 x 25 x 1.6 mm3. The research, published in Engineering Science and Technology, an International Journal, suggests that adding the 6 GHz spectrum as a Wi-Fi 6E may assist in reducing traffic on other bands, but the large bandwidth raises antenna design difficulties.
