“…For the wireless communication, various graphene-based patch antennas with low profiles and small sizes have also been comprehensively studied. The adopted graphene monolayer offers the possibilities to actively control the directivity, and bandwidth of the patch antenna [105][106][107][108][109][110]. The graphene monolayer has also been reported to fabricate the radio frequency identification tag [111][112][113], and realize the multiple-input multiple-output antenna system with tunable beamwidth and radiation direction [114,115].…”

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.

Terahertz (THz) technology can be widely used in radar, remote sensing, homeland security and counter-terrorism, high-secret data communication and transmission, atmospheric and environmental monitoring, real-time biological information extraction, and medical diagnosis. It is the frontier of current research. However, most of highly sensitive THz detectors work in a relatively narrow frequency range. It attracts great attention to design a high-gain terahertz antenna operates in a wide spectrum range. In this paper we propose a new structure of fractal butterfly antenna with high gain which can be used for broadband THz detection. This fractal butterfly antenna is constructed by independent fractal unit groups on butterfly antenna, which simplifies the antenna manufacturing process and reduces the manufacturing cost. The antenna can operate in the 0.1-10 THz frequency band, with impedance bandwidth of 85% resonated at 4.9 THz, return loss of as small as -33.59 dB, and maximum gain of 16.95 dB. Among the antenna with 3 to 4 fractal unit groups, the best operation band of the antenna is 6.2-6.4 THz. The proposed fractal butterfly antenna can effectively improve the performance of terahertz detectors, and provide the possibility for detection research in higher frequency bands.

“…Nevertheless, one disadvantage of using a conventional copper conducting material antenna is the possibility for copper failure because of the recurrent bending and deformations. To address a few of these challenges, a flexible graphene-based conducting material is used to replace the etched copper in conventional antennas [2,3].…”

Variety of materials with different dielectric constants are available for microstrip patch antenna. In the paper, graphene material is used and analyzed at X-band frequency. The use of graphene patch material as conducting substance for the antenna is assumed to improve the bandwidth and radiation efficiency on account of the outstanding functionalities and electromagnetic properties. The antenna is designed with Duroid RT5880 (lossy) material with a dielectric constant of 2.2 palced between graphene patch and ground plane using Computer Simulation Tool (CST) Microwave Studio 2016. The resonance frequency of the antenna is 10.54 GHz with a gain of 7.86dB, return loss of-24.55 dB, directivity of 8.31 dBi and VSWR of 1.1.2. The antenna operates for frequencies from 8-12 GHz with an enormous bandwidth of 1.09GHz.
