In this work, a printed coplanar waveguide (CPW) fed single band antenna based on expanded graphite material is introduced. The proposed antenna is based on a CPW-monopole antenna with a U-shape conductor strip connected with the ground. Expanded graphite, a grade of graphene, is used as a conductor to design the uniplanar antenna over a flexible paper substrate. The antenna is designed for 2.4 GHz applications. The antenna design procedures are discussed. The material preparation and analysis are illustrated. Finally, the antenna fabrication and measurements of the reflection coefficient are discussed. The measured antenna reflection coefficient agrees with the simulated one, ensuring the antenna validity for serving the required applications. The radiation antenna parameters are discussed and simulated results from two-simulation software are included for comparison. The antenna has a simulated gain of 4 dBi and simulated efficiency of around 90% at 2.4 GHz.

In this study, the effects of graphene and design differences on bow-tie microstrip antenna performance and bandwidth improvement were investigated both with simulation and experiments. In addition, the conductivity of graphene can be dynamically tuned by changing its chemical potential. The numerical calculations of the proposed antennas at 2–10 GHz were carried out using the finite integration technique in the CST Microwave Studio program. Thus, three bow-tie microstrip antennas with different antenna parameters were designed. Unlike traditional production techniques, due to its cost-effectiveness and easy production, antennas were produced using 3D printing, and then measurements were conducted. A very good match was observed between the simulation and the measurement results. The performance of each antenna was analyzed, and then, the effects of antenna sizes and different chemical potentials on antenna performance were investigated and discussed. The results show that the bow-tie antenna with a slot, which is one of the new advantages of this study, provides a good match and that it has an ultra-bandwidth of 18 GHz in the frequency range of 2 to 20 GHz for ultra-wideband applications. The obtained return loss of −10 dB throughout the applied frequency shows that the designed antennas are useful. In addition, the proposed antennas have an average gain of 9 dBi. This study will be a guide for microstrip antennas based on the desired applications by changing the size of the slots and chemical potential in the conductive parts in the design.

“…A broadband microstrip antenna design of hexagonal shape is proposed 34 under the frequency spectrum of 4.7 to 6.7 GHz and tested on VNA developed by Agilent technologies which shown better results in terms of reflection coefficient and gain but factors like voltage standing wave ratio (VSWR) and radiation efficiency are not appropriate. A complete functional prototype was designed and tested by authors in Reference 35 at the frequency ranging from 3.55 to 4.42 GHz. Two circular patches are used along with a rectangular patch as two layer design which was implemented on a vehicle for communicating with another vehicle.…”

The article proposes a microstrip patch antenna for vehicular communication applications under 5G communication frequency band. The dimensions of the antenna play an important role in the field of vehicular communication applications. The antenna dimensions are optimized by introducing back propagation algorithm. Overall dimension of the antenna is reduced by 16% as compare to the traditional formulations. Further fractal geometry is implemented on the patch and recessed ground as defected ground structure. FR4 epoxy is used to construct the substrate of the proposed antenna with the dimensions of 50 mm × 60 mm × 1.6 mm and the patch is designed as rectangular patch with H‐cut and I‐cut. The proposed antenna is simulated using Ansys high frequency structure simulator v15 and the frequency of operation is 27 to 33 GHz. The antenna parameters such as reflection coefficient, voltage standing wave ratio, gain, radiation, and current distribution are investigated. The antenna is designed in compact in shape such that it is suitable for vehicular communication applications.
