Abstract
Current research on tunable patch antennas for wireless applications has mostly focused on the dimensional variations of patch elements, such as geometry and substrate materials, using different techniques to achieve the reconfiguration. The use of different mixing materials to ensure reconfiguration and improvement of antenna performance in microwave frequencies has not yet been studied thoroughly. In this article, we consider graphene as a patch material, due to its unique chemical, mechanical, electronic, thermal and optical features, which assist in providing a highly flexible and adaptive antenna. The proposed antenna is a square plate excited by a coaxial probe, operating at a 2.45GHz spectrum. Adding graphene to the antenna structure and tuning its chemical potential, a frequency reconfiguration from 2.36GHz to 1.26GHz is obtained. This antenna can be deployed in many communication systems. Results demonstrate the importance of this material in the development of nanoelectronics in the future.
