“…In this paper, a thin graphene sheet is pated on 100 µm thick paper and cut in the shape of a patch using g commercially available micro-cutter. Another fabrication approach is given by Zhou et al (2020) in which a conductive ink was made by mixing graphene flakes with N-Methyl-pyrrolidone (NMP) then, the desired pattern was printed on a paper substrate using screen-printing technology. The operating frequency is 5.8 GHz for wireless communication applications.…”

One of the strongest and thinnest substances known to exist is graphene. It can be efficiently used for antenna fabrication and significant benefits can be analyzed such as size miniaturization, gain and return loss enhancement, flexibility and increase in bandwidth, etc. In this paper, a graphene patch antenna has been designed and fabricated for 5G applications at 28.3 GHz. Different 5G frequency allocation throughout the world is shown in tabular form. Photonic crystal substrate is used to reduce surface wave loss which in turn, increases the radiation efficiency of the antenna. The ground plane is made up of copper, treated as a Perfect Electric Conductor Several unique properties of graphene are analyzed and shown. Then, a thin graphene sheet is used as a patch and an antenna is designed and fabricated. The patch has dimensions of 3.4 mm by 2.38 mm. The simulated return loss is maximum at −33.69 dB at 28.3 GHz, whereas for the measured design it is −26.31 dB at 28.04 GHz. It is observed that graphene can be a good alternative to existing conductors, especially at higher frequencies. The proposed antenna is designed and simulated using HFSS software.

“…Flexible antennas using graphene are promising due to their decent electrical conductivity and excellent mechanical properties. Graphene paper [ 31 ], graphene nanoflake ink [ 32 , 33 ], graphene oxide ink [ 34 ], and graphene nanoparticle ink [ 35 ] have been used in prior studies for fabricating flexible antennas. The performance of flexible antennas relies heavily on the fabricated conducting traces with high deformation sustainability while maintaining electrical conductivity [ 36 ].…”

The field of flexible antennas is witnessing an exponential growth due to the demand for wearable devices, Internet of Things (IoT) framework, point of care devices, personalized medicine platform, 5G technology, wireless sensor networks, and communication devices with a smaller form factor to name a few. The choice of non-rigid antennas is application specific and depends on the type of substrate, materials used, processing techniques, antenna performance, and the surrounding environment. There are numerous design innovations, new materials and material properties, intriguing fabrication methods, and niche applications. This review article focuses on the need for flexible antennas, materials, and processes used for fabricating the antennas, various material properties influencing antenna performance, and specific biomedical applications accompanied by the design considerations. After a comprehensive treatment of the above-mentioned topics, the article will focus on inherent challenges and future prospects of flexible antennas. Finally, an insight into the application of flexible antenna on future wireless solutions is discussed.

“…For example, T. Leng et al [ 23 ] presented a dual-band graphene antenna for WiFi frequencies; this antenna was printed on a paper substrate. Furthermore, in [ 24 ] and [ 25 ], the authors showed graphene array antennas printed on paper for WiFi bands and Sub-6 GHz 5G mid-bands, respectively. Another example of printed graphene antennas was reported by K. Pan et al [ 26 ], who designed an ultra-wideband monopole with printed graphene with a frequency range from 4 to 14 GHz.…”

In this paper, a dual-band graphene coplanar waveguide antenna is designed for smart cities and internet of things applications. A graphene film is chosen as the conductive material for the radiation patches and ground plane with a thickness of 240 μm and an electric conductivity of 3.5 × 105 S/m. The dielectric is glass with a dielectric permittivity of 6 and a thickness of 2 mm. The implementation of the antenna on glass permits the integration of the antenna in smart cities and IoT applications. This antenna is based on two trapezoidal patches that generate the dual-band behavior. The overall dimensions of the antenna are 30 mm × 30 mm × 2 mm. The reflection coefficient, gain, and radiation patterns were measured and compared with the simulations. The antenna covers two frequency bands; the lower band covers the 2.45 GHz ISM band, and the upper band range covers from 4 to 7 GHz.
