Nanotechnology is providing a new set of tools to design and manufacture miniaturized devices such as sensors or on/off chips networks. Such devices require wireless communications for information sharing and coordination. Unfortunately, reducing the size of a classical metallic antenna down to a few micrometres would impose the use of very high resonant frequencies, from the near infrared to the optical ranges (tens of hundreds of THz). This would drastically limit their communication range and require the implementation of transceivers able to operate at this extremely high frequency. Graphene offers a new approach to radically downscale antennas thanks to its ability to support the propagation of Surface-Plasmon Polariton (SPP) waves in the terahertz frequency band. Graphene micro-antennas provide a better integrability for future miniaturized wireless systems and represents an enabling technology for applications such as Wireless NanoSensor Networks, Internet of Things and On/Off-Chip Wireless Networks. In this talk we will describe the fundamental properties behind graphene miniaturized antennas, its applications as well as the status of its experimental demonstration.
