“…2 illustrates the comparison of various dual-band antennas from the literature where it is observed that the proposed fractal antenna achieves low profile, satisfactory gain, and application bands not covered by other antennas, especially in the sub-6-GHz 5G regime. The physical size of the antennas reported in previous studies 6,[20][21][22]24,26,27 is quite larger compared to the proposed one whereas the antenna in previous studies 20,22,25,27 have lower impedance bandwidth for the dual-band operations. The antenna in Karimbu Vallappil et al 21 and Nhlengethwa and Kumar 27 has inferior gain and bandwidth in comparison to the designed fractal antenna.…”

“…4 The multiband behavior of the Sierpinski fractal antenna is discussed in Punete et al 5 The self-similarity property of the fractal antenna is mainly responsible for the electromagnetic behavior of the antenna. The star-shaped fractal antenna is developed for the L and S band application, which is discussed in Malallah et al 6 In this article, the fractal geometry slot has been designed using four squares rotating in four angles and forming 16 slots. The radiator was designed with a fusion of fractal shape and meander lines.…”

Summary In this article, a split‐ring resonator‐inspired fractal antenna for the GSM and sub‐6‐GHz 5G applications is presented. The antenna geometry uses a combination of square‐shaped split‐ring resonators arranged in a Sierpinski fractal arrangement that is realized on a low‐cost FR4 substrate. The overall dimension of the proposed antenna is 0.35λ × 0.35λ mm2 (lowest frequency). The antenna resonates at a dual‐frequency band spanning from 1.75 to 2.0 (13.36%) and 3.01 to 4.18 GHz (33.42%) with a peak gain of 1.5 and 2.05 dBi at respective resonant peaks that correlate satisfactorily with the measured values. The proposed antenna uses Sierpinski fractal geometry on the top and the partial ground plane at the back with dipole‐shaped radiation patterns, and an efficiency of around 80% makes the antenna commercially suited for the GSM and sub‐6‐GHz 5G communication applications.

The study and exploration of massive multiple-input multiple-output (MMIMO) and millimeter-wave wireless access technology has been spurred by a shortage of bandwidth in the wireless communication sector. Massive MIMO, which combines antennas at the transmitter and receiver, is a key enabler technology for next-generation networks to enable exceptional spectrum and energy efficiency with simple processing techniques. For massive MIMOs, the lower band microwave or millimeter-wave band and the antenna are impeccably combined with RF transceivers. As a result, the 5G wireless communication antenna differs from traditional antennas in many ways. A new concept of the MIMO tri-band hexagonal antenna array is being introduced for next-generation cellular networks. With a total scaling dimension of 150 × 75 mm2, the structure consists of multiple hexagonal fractal antenna components at different corners of the patch. The radiating patch resonates at 2.55–2.75, 3.45–3.7, and 5.65–6.05 GHz (FR1 band) for better return loss (S11) of more than 15 dB in all three operating bands. The coplanar waveguide (CPW) feeding technique and defective ground structure in the ground plane have been employed for effective impedance matching. The deviation of the main lobe of the radiation pattern is achieved using a two-element microstrip Taylor antenna array with series feeding, which also boosts the antenna array’s bandwidth and minimizes sidelobe. The proposed antenna is designed, simulated, and tested in far-field radiating conditions and generates tri-band S-parameters with sufficient separation and high-quality double-polarized radiation. The fabrication and testing of MIMO antennas were completed, where the measurement results matched the simulation results. In addition, the 5G smartphone antenna system requires a new, lightweight phased microwave antenna (μ-wave) with wide bandwidth and a fire extender. Because of its decent performance and compact architectures, the proposed smartphone antenna array architecture is a better entrant for upcoming 5G cellular implementations.

“…As a result, researchers and practitioners alike have a strong interest in antennas that are both small and capable of handling several frequencies. The employment of multiple resonance techniques has been the primary focus of research into these antennas [2]. One of the most significant aspects of an ongoing investigation into the system level is to incorporate wideband and multiple-band response, even though maintaining proper radiation pattern and miniaturizing antenna are the two most present issues [3].…”

High-speed wireless communication devices need antennas to operate at multiple frequencies with high gain. The need for such antennas is increasing day by day. The proposed metamaterial superstrate antenna gives a high gain and multiband performance, which is required in high-speed wireless communication devices. The designed antenna is also applicable for C- and X-band communication devices. The structure consists of a simple patch and multiple split-ring resonator metamaterials on the superstrate region. The performance optimization is achieved by adjusting the feed position, varying the height of the superstrate layer and changing the thickness of metamaterial rings. The proposed design is analyzed for 4 GHz to 12 GHz. The performance analysis regarding the reflection coefficient, directivity, gain and electric field is observed. FR4 is used as a dielectric material that makes the design low-cost. The proposed design represents a minimum reflection coefficient response of −49 dB, a bandwidth of 490 MHz, a maximum electric field of 1.29 × 104 v/m, good directivity and a broader radiation pattern. The comparison between the simulated and the measured results is incorporated in the manuscript. A comparison of the presented design with other articles is included to check the novelty of the design. The proposed method helps to target applications such as WiFi, Earth observation and microwave links.
