This paper aims to model and analyze planar antennas for high frequencies using an iterative wave design procedure (WCIP). The formulation adopted in the method allowed determining a basic equation for the interaction of linearly combined electromagnetic fields with the incident and reflected waves in various dielectric media over a discontinuity. In this paper, we design a broadband terahertz patch antenna using graphene. We propose to design a new numerical tool to model the implementation of graphene to achieve an efficient and flexible antenna. The design methodology started with the design of a compact conventional microstrip antenna for 118.87 GHz, and the antenna was then miniaturized using rectangular slots. Based on the simulation results, the suggested structure antenna with a slot can offer great characteristics in terms of broadband performance and frequency reconfiguration using various voltages on the graphene. The antenna provides frequency bands f r1 = 118.7 GHz, f r2 = 120 GHz, f r3 = 123.36 GHz, f r4 = 128.27 GHz, f r5 = 131 GHz, and f r6 = 132.8 GHz with bandwidths ∆f r1 = 9.5 GHz, ∆f r2 = 3.66 GHz, ∆f r3 = 4 GHz, ∆f r4 = 3.23 GHz, ∆f r5 = 3.401 GHz, ∆f r6 = 3.01 GHz and uniform radiation patterns, the value of VSWR between 1 and 2 for different chemical potential values respectively µ c = 0.1 eV, µ c = 0.2 eV, µ c = 0.3 eV, µ c = 0.4 eV, µ c = 0.5 eV, µ c = 0.6 eV using polyimide with a dielectric constant of 3.5 and a loss tangent of 0.008. In addition, we studied the effect of different substrate materials (Arlon and Duroid 5880). The simulation is performed using a new WCIP equation, and the validation is performed by comparison with the finite integration method in technique (FIT). A comparison of the computation time is presented in this paper.

“…With the advantages of superior properties such as high thermal conductivity, phased array antennas constructed on the conductive material carbon materials film were developed for 5G millimeter-wave applications. In comparison to a copper linear array, the Graphene-assembled film (GAF) linear proposed antenna has an operating bandwidth that is 212.5 percent wider and side lobes that are 5 dB lower [24]. The bottom plate of the substrate-integrated doubleline is built with coupling slots for the proposed antenna's microstrip-to-substrate-integrated doubleline transition.…”

A wide variety of technologies are included in various networks under the 5G umbrella. The international telecommunication union (ITU) has given the name "fifth-generation mobile communication systems" to recent millimeter-wave communication technology.Millimeter-wave technology, in general terms, encompasses the electromagnetic spectrum between 30 to 300 GHz, which refers to wavelengths ranging from 10 to 1 mm. The growing memory capacity in handheld connectivity is predicted to produce a high data rate of 10 Gbit/s, which relates to the progression of graphics and data-storage technology. Every indoor wireless communication systems have mixers, amplifiers, antennas, and filters which are essential components of an radio frequency (RF) radio frequency front-end circuit. The demand for microstrip antennas in femtocells plays an important role which can work in both unlicensed or licensed spectrums.*Author for correspondence Femtocells are energy efficient, low cost, selfinstallable, and can be easily manufactured with fifth generation (5G)frequency bands [1]. As the size of the antenna required for 5G femtocells is small, lowprofile antennas like millimeter-wave antennas can be easily preferred where it carries low power and provide enormous bandwidth for communication purpose. In 2019, the Telecom Regulatory Authority of India (TRAI) has given 5G service and sufficient spectrums which are made for the auction.

As theoretical research further develops, coding metasurfaces have been widely studied and applied due to their uniqueness in digital characterization and sequence arrangement. In this work, based on highly conductive graphene‐assembled film (GAF), an ultralight anisotropic broadband coding metasurface (ABCM) is proposed. The GAF ABCM consists of 16 units with specific phase responses and enables complete metal substitution. By arranging the unit cells in a specific order, the GAF ABCM realizes the functions of anomalous reflection, polarization conversion, and radar cross‐section (RCS) reduction. Results validate that the GAF ABCM has a measured 10 dB normal incidence backward RCS reduction within the working frequency band of 7–18 GHz, which fully covers the X‐band and Ku‐band for radar application. Furthermore, due to the lightweight property of GAF, the density of the GAF ABCM is only 0.06 g/cm3 (surface mass density of 0.038 g/cm2). All results indicate that the lightweight GAF metasurface is promising in radar stealth and communication fields.
