Researchers at the University of Manchester, along with UK graphene manufacturer BGT Materials, printed a radio frequency antenna using compressed graphene ink.The antenna worked well enough to make it practical for use in radio-frequency identification (RFID) tags and wireless sensors, according to the researchers. DESIGN AND PERFORMANCE INVESTIGATION OF TUNABLE UWB THZ ... In this paper a tunable antenna using graphene-based fractal shape artificial magnetic conductor (AMC) is proposed for ultra-wideband (UWB) terahertz (THz) application. The resonance frequency of the proposed antenna can be tuned by varying the Electrically tunable mid-infrared antennas based on VO2

Carbon and 2D electronics | IESL-FORTH The activity concentrates on the sources of high quality material and its manipulation. Two large categories of materials are the focus here: Regarding carbon nanotubes (CNTs) it is critical to control the chirality, diameter, placement and surface functionalization of the nanotubes used in various applications.Our aim so far has been to control surface functionalization and deposition methods ...
Basic Antenna Theory. · Every structure carrying RF current generates an electromagnetic field and can radiate RF power to some extent. · A transmitting antenna transforms the Radio Frequency (RF) energy produced by a radio transmitter into an electromagnetic field that is radiated through space.
A design for a broadband single-layer dual-band reflectarray antenna is presented. A genetic algorithm is employed to design and optimize the element of the antenna. The basic idea to improve the bandwidth of the proposed antenna is based on increasing the range of the linear region of the phase response of the microstrip element.

Low-cost RF antenna printed with graphene ink — could soon ... To create the graphene ink-based RF antenna, the researchers mixed graphene flakes with a solvent. Typically, the next step is to add a binder like ethyl cellulose to help the ink stick — it also helps the graphene conduct electricity better than binder-free ink. Martino Aldrigo - Academia.edu A tunable microwave slot antenna based on graphene more by Martino Aldrigo and Alina-Cristina Bunea ABSTRACT The paper presents the experimental and modeling results of a microwave slot antenna in a coplanar configuration based on graphene. Graphene-Based Nano-Antennas May Enable Networks of Tiny Machines The next step will be to actually fabricate a graphene nano-antenna and operate it using a transceiver also based on graphene. “Our project shows that the concept of graphene-based nano-antennas is feasible, especially when taking into account very accurate models of electron transport in graphene,” said Akyildiz.
