“…The work reported here differs from the research in by (1) presenting the new model of the graphene‐based conductors for the design of conformal monopole antennas on paper substrates and (2) showing the mechanical benefits of graphene‐based conductors over traditional copper conductors. These conductors have applications in load bearing antennas, wearable antennas, conformal antennas on the side of military equipment and aircraft.…”

“…Recently, new composite materials with structural strength and high electrical conductivity have been designed by embedding graphene‐based materials into the lattice . Antenna fabrication and related works have been investigated where graphene‐based conductors were used as conducting materials. The graphene‐based materials provide the electrical conductivity in these composites and when isolated they are very flexible, making them possible for conformal antenna applications.…”

Two key components, among several, in the design of a conformal antenna are the planar conductors and the flexible substrates. In this paper, a new approach of using graphene‐based conductors instead of copper conductors in the design of a conformal antenna is presented. To determine the conductivity properties of the graphene‐based conductor, the copper conductors in a well‐known micro‐strip transmission line (TL) and micro‐strip antenna were replaced with the graphene‐based conductors and were analytically evaluated, simulated in a full‐wave simulation software and experimentally tested. Overall, it was shown that these graphene‐based conductors have a conductivity that is high enough to design a useful micro‐strip TL and micro‐strip antenna. In particular, a conductivity of σ = 1.94 × 105 S/m for a 25 µm thick graphene‐based conductor was determined from 100 MHz to 4.0 GHz. Finally, the conformity of the graphene‐based conductors was demonstrated using a mechanical test fixture and by designing a monopole antenna on a 100 µm thick paper substrate. In summary, the results in this paper show that the graphene‐based conductors provide an alternative to the potentially fragile copper conductors traditionally used to design conformal antennas. © 2017 Wiley Periodicals, Inc.

“…On the other hand, graphene‐based antennas could provide new features in RF devices. Graphene, either in its single layer and multi‐layer form, has a lot of unique properties like high conductivity of 6000 S/cm and extreme high thermal conductivity of 5000 W·m −1 ·K −1 , which is very suitable for RF antenna design . As far as we know, most investigations of graphene‐based antennas are focused in THz band .…”

“…A coil structure, matching circuit, and magnetic shielding structure are considered to improve power transfer efficiency. [7][8][9][10] In previous research, the leakage magnetic field was reduced either by using magnetic material to adjust the magnetic flux path or by using conductive material to cancel the magnetic field. 11,12 This paper proposes a modified shielding structure with the ferrite and aluminum that can reduce the leakage magnetic field while maintaining high-power transfer efficiency.…”

In this paper, rectangular dielectric resonator antennas (RDRAs) fed by offset tapered copper and graphene microstrip lines are presented. A comparison between these two feeding materials is made with an aim of using the high‐conductivity graphene film (HCGF) to replace copper for feeding the RDRA if feasible. Four feed forms have been discussed. The presented feed mechanism is able to couple electromagnetic energy in three different modes of the RDRA. The HCGF is utilized to replace copper for feeding the RDRA. An impedance bandwidth of 11.32% (3.25 GHz ~ 3.64 GHz) is realized in the experiments by using a graphene feed line, compared to that of 12.24% (3.22 GHz ~ 3.64 GHz) for copper, and a peak gain of 4.48dBi is obtained at the center frequency. The results show that the HCGF can be used to couple the RDRA, and the HCGF fed RDRA has good performance. Radiation patterns around the center frequency are also presented.

Graphene antennas and relevant microwave devices have attracted wide attention due to their lightweight, low-cost, and flexible characteristics. However, their performances are usually not satisfactory because of low conductivity of graphene materials in the macroscopic scale. In this article, an antenna array made of flexible high-conductivity graphene materials is fabricated and reported for potential application in 5G mobile communications. The antenna array has a high gain of 6.77 dBi at 3.51 GHz with an excellent return loss, which is comparable to the identical copper counterpart. Moreover, the graphene antenna has similar radiation patterns to the copper antenna.
