Recently, there have been notable advancements in wireless communication systems to address the deficiencies of fourth generation (4G) wireless technology, such as insufficient spectrum bandwidth, slow data transfer rates, and constrained network capacity. These issues may be addressed in fifth generation (5G) wireless technology, which is no longer stand-alone. This article proposes and designs a defected ground slotted patch antenna (DGSPA) for 5G (Sub-6 GHz band) applications. It can work at 3.5 GHz in the 5G N77 band, Sub-6 GHz 5G, LTE Band 42, and WiMAX. The suggested antenna has an overall dimension of 38×38×1.575 mm3 and is built on the Rogers RT5880 substrate material, whose dielectric permittivity is 2.2. The CST software is used as the simulation tool to analyze the designed antenna’s performance. The novelty of the recommended antenna is in terms of its small size with defective ground structure (DGS), high antenna gain, perfect impedance matching, and improved impedance bandwidth. The role of the DGS is evaluated by comparing the antenna’s performance with and without the DGS. It has been noticed that the DGS-backed antenna had an impedance bandwidth improvement of more than 11MHz, whereas the impedance profile is (50.086−????0.179) Ω, which denotes 50 Ω pure resistivity. It will operate within the frequency range of (3.4828 - 3.522) GHz with an impedance bandwidth of 69.2 MHz. The proposed antenna’s reflection coefficient (|????1,1|) is obtained as -54.028 dB at the resonating frequency of 3.5176 GHz, whereas the radiation gain and efficiency are observed as 6.463 dB and 93.475%, respectively. Thus, due to its promising performance based on radiation pattern, optimum efficiency, and higher bandwidth, the recommended defected ground slotted patch antenna can efficiently be used for the application of Sub-6 GHz 5G services.

“…Broad band metasurface [20] is used for polarization independent wave focusing. Gain enhancement of sub 6 GHz band 5G applications [21] is done by metasurface that possesses epsilon near zero property. The majority of metamaterial superstrates have the disadvantages of being inflexible, employed in the high frequency zone, and constructed using expensive substrates to achieve minimal loss.…”

This paper proposes a new low loss high dielectric substrate made of CaTiO3 incorporated butyl rubber (CBR). The synthesized material has a dielectric loss of 0.0048 and dielectric constant of 11.7. A novel circular anisotropic structure is used in the design of metamaterial unit cell. This metamaterial structure exhibits near-zero refractive index at 2.4 GHz. The extraction of refractive index is done from the scattering parameters using generalised sheet transition condition. An array of 3×3 unit cell is the metasurface superstrate, which is proposed for the gain enhancement. It is kept above the microstrip patch antenna working at 2.4 GHz. The proposed superstrate provides a gain enhancement of 4.6 dB. The height between the antenna and superstrate is optimized to 0.088 λ. The enhancement of gain on metasurface substrate with different loss tangents is analyzed. The simulation and measurement results of antenna with superstrate show good agreement with a peak gain of 7.6 dBi. The radiation efficiency of the antenna is increased by 42%.

“…Due to the growth of the fifth generation (5G) wireless system, the types of antenna devices have subjected for the high-performance requirement [13]. The recent 5G antenna work has been proposed in a Sub-6 GHz band using a patch antenna with a metamaterial superstate, but it comes up with a bulky structure that is unsuited for a thin profile due to the air space as an antenna height [14]. The planar configuration has a physical benefit which contribute to the compact system integration.…”

A 5G wireless system requests a high-performance compact antenna device. This research work aims to report the characterization and verification of the artificial magnetic conductor (AMC) metamaterial for a high-gain planar antenna. The configuration is formed by a double-side structure on an intrinsic dielectric slab. The 2-D periodic pattern as an impedance surface is mounted on the top surface, whereas at the bottom surface the ground plane with an inductive narrow aperture source is embedded. The characteristic of the resonant transmission is illustrated based on the electromagnetic virtual object of the AMC resonant structure to reveal the unique property of a magnetic material response. The characteristics of the AMC metamaterial and the planar antenna synthesis are investigated and verified by experiment using a low-cost FR4 dielectric material. The directional antenna gain is obviously enhanced by guiding a primary field radiation. The loss effect in a dielectric slab is essentially studied having an influence on antenna radiation. The verification shows a peak of the antenna gain around 9.7 dB at broadside which is improved by 6.2 dB in comparison with the primary aperture antenna without the AMC structure. The thin antenna profile of λ/37.5 is achieved at 10 GHz for 5G evolution. The emission property in an AMC structure herein contributes to the development of a lowprofile and high-gain planar antenna for a compact wireless component.
