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.

Designing antennas for vehicular communication systems presents several unique challenges due to the dynamic nature of vehicular environments, mobility, and the need for reliable connectivity. A wider bandwidth is a critical requirement of vehicular antennas. In this paper, a super-wideband FR4 epoxy-based low-cost meander line patch antenna is designed for fifth-generation (5G) vehicular mobile frequency applications. The proposed antenna is excited through a microstrip feedline on top of the substrate with a continuous ground plane. The meander line is implemented through a theoretical formula to cover upper-5G frequency range 1 (FR1) and frequency range 2 (FR2). The proposed antenna has 7.5 dBi peak gain when operated at 28 GHz. The simulated bandwidth ratio (BWR) is 9.09:1 for a −10 dB reflection coefficient covering a 53.4 GHz (6.6 GHz to 60 GHz) frequency range. The proposed antenna has a linear meander line planar structure, occupies a small area of 34 mm × 20 mm × 1.6 mm, and satisfies the bandwidth requirements of 5G millimeter-wave and sub-bands of the sixth generation for vehicular applications.

“…Another technology proposed to implement dual-band operations is metasurfaces in which the unit cells consist of sub-wavelength resonators [39]. Nevertheless, also with this solution, reconfigurability comes at the cost of a relatively reduced frequency ratio (e.g., X-and Ku-band) [40]- [42].…”

The subject of this work is the numerical design of a plasma-based dual-band reflective surface. The proposed concept consists of a series of cylindrical plasma discharges placed on top of a reconfigurable surface made of conventional metallic patches. The possibility to independently control the steering of two signals, one in Ku-band (12.5 GHz) and the other in Ka-band (27.5 GHz), with a frequency ratio larger than 2, is proven. The signal at a lower frequency is controlled via the plasma density, while the one at a higher frequency is reconfigured via the conventional metallic surface. Notably, the larger the difference between the two working frequencies, the more a plasma-based reflecting surface suits dual-band operations.INDEX TERMS Gaseous plasma antennas; Reflective surfaces; Dual-band; Ku-band; Ka-band.
