Development of Graphene Based Tapered Slot Antennas for ... antenna with graphene control has been developed in [16] for 1THz applications. The reconfigurable characteristic of the antenna was obtained due to the tunable graphene conductivity. In microwave frequency range, flexible graphene based conductor (GBC) sheet is used to design a UWB antenna Graphene Antennas: Can Integration and Reconfigurability ... Based on these observations and different graphene antenna simulations from microwave to terahertz, we will discuss the issue of antenna efficiency, integration and reconfigurability, as function of the operation frequency range. While the use of graphene for antennas at microwave appears extremely limited,
The paper presents the experimental and modeling results of a microwave slot antenna in a coplanar configuration based on graphene. The antennas are fabricated on a 4 in. high-resistivity Si wafer, with a ∼300 nm SiO2 layer grown through thermal oxidation. A CVD grown graphene layer is transferred on the SiO2. The paper shows that the reflection parameter of the antenna can be tuned by a DC ...

Tunable antenna radome based on graphene frequency ... In this paper, a graphene-based frequency selective surface (FSS) is proposed. The proposed FSS exhibits a tunable bandpass filtering characteristic due to the alterable conductivity of the graphene strips which is controlled by chemical potential. Based on the reconfigurable bandpass property of the proposed FSS, a cylindrical antenna radome is designed using the FSS unit cells. Microwave Study of Field-Effect Devices Based on Graphene ...
