This paper describes the design and simulation of a compact CPW fed graphene patch antenna with Z shape slot. Antenna design is enhanced by the introduction of a ‘Z’ shaped slot in the patch of the antenna, that make it compact. Antenna resonates at the frequency of 2.4 GHz, for Wi-Fi uses. Polyamide Kapton tape of thickness 100µm and relative permittivity of 3.5 is used as the substrate. Graphene is used to make the conducting patch, feed and grounds of the antenna design. Various antenna parameters including reflection coefficient, radiation patterns and surface currents and parametric study of a physical parameter related to antenna design are discussed. The proposed antenna is ~20% smaller than the patch antenna at the same resonance frequency.

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.

“…[ 5 , 18 , 19 ]. Finally, the designs of graphene antennas allow one to vary operation in the frequency range of 2–14 GHz [ 1 , 19 , 20 , 21 ]. Moreover, it should be noted that the 5.7–5.8 GHz band, which is part of the 5G standard, is in demand of the Internet of Things both for smart cities and for the transmission of wearable electronics in order to transmit data from a person.…”

Benefits of Printed Graphene with Variable Resistance for Flexible and Ecological 5G Band Antennas

et al. 2022

The possibility of creating antennas of the 5G standard (5.2–5.9 GHz) with specified electrodynamic characteristics by printing layers of variable thickness using a graphene suspension has been substantiated experimentally and by computer simulation. A graphene suspension for screen printing on photographic paper and other flexible substrates was prepared by means of exfoliation from graphite. The relation between the graphene layer thickness and its sheet resistance was studied with the aim of determining the required thickness of the antenna conductive layer. To create a two-sided dipole, a technology has been developed for the double-sided deposition of graphene layers on photographic paper. The electrodynamic characteristics of graphene and copper antennas of identical design are compared. The antenna design corresponds to the operating frequency of 2.4 GHz. It was found that the use of graphene as a conductive layer made it possible to suppress the fundamental (first) harmonic (2.45 GHz) and to observe radiation at the second harmonic (5.75 GHz). This effect is assumed to observe in the case when the thickness of graphene is lower than that of the skin depth. The result indicates the possibility of changing the antenna electrodynamic characteristics by adjusting the graphene layer thickness.
