Graphene is an ideal 2D material system bridging electronic and photonic devices. It also breaks the fundamental speed and size limits by electronics and photonics, respectively. Graphene offers multiple functions of signal transmission, emission, modulation, and detection in a broad band, high speed, compact size, and low loss. Here, we will have a brief view of graphene based functional devices at microwave, terahertz, and optical frequencies. Their fundamental physics and computational models will be discussed as well.

This paper presents a novel tunable terahertz antenna based on a hybrid graphene-metal structure fed by a waveguide. First, the hybrid plasmonic waveguide is studied by analytical and numerical methods. Then, an efficient terahertz antenna is designed by an analytical approach using the transmission line model. The antenna performances are evaluated in the terahertz frequency band by a full-wave electromagnetic solver. Contrary to previous terahertz antennas based on graphene, the results show that the proposed antenna has satisfactory radiation efficiency and gain. Moreover, this study demonstrates that the reflection parameter of the antenna can be tuned by the chemical potential of graphene. The proposed antenna can be applied for terahertz applications such as wireless communication in interand intra-chip devices and sensing.

“…First works on propagation of terahertz waves over graphene sheets led to a surge of proposals that, in essence, consist of a number of finite-size graphene layers (the radiating elements) mounted over a dielectric material and a feed to drive the signals to the antenna [4]. These antennas have been studied from different perspectives, namely: Antenna dimensions: We use CST MWS [9] to simulate the dipole shown in Fig.…”

Abstract-Graphene is enabling a plethora of applications in a wide range of fields due to its unique electrical, mechanical, and optical properties. In the realm of wireless communications, graphene shows great promise for the implementation of miniaturized and tunable antennas in the terahertz band. These unique advantages open the door to disruptive wireless applications in highly integrated scenarios where conventional communications means cannot be employed. In this paper, recent advances in plasmonic graphene antennas are presented. Wireless Networkon-Chip (WNoC) and Software-Defined Metamaterials (SDMs), two new area-constrained applications uniquely suited to the characteristics of graphene antennas, are then described. The challenges in terms of antenna design and channel characterization are outlined for both case scenarios.
