“…Sub-6 GHz bands (usually less than 6 GHz) provide a balance between greater coverage and higher data speeds than regular 4G LTE. Recent research has focused on dual-band microstrip designs suited for these bands, [17,18]. A Sohrabi, H Dashti, and J Ahmadi-Shokouh achieved a highly electrically small antenna with a 10 dB impedance bandwidth of 220 MHz, covering a 2.28-2.5 GHz band.…”

In this paper, two novel compact low-profile dual-band plasmonic antennas designed with the help of Characteristic Mode Analysis and parametric study are presented. The plasmonic antennas contain microstrip line-fed strip-loaded patches and partial ground planes. The final proposed antennas cover the two bands in the frequency range of 2.4-2.5 GHz and 5-6 GHz. Plasmonic antennas offer nearly omnidirectional patterns at the desired frequency ranges. Additionally, a detailed parametric study of almost all the design parameters is performed to display the effect of varying those parameters on the resonance frequency at both bands. The parametric study for both antennas has been carried out to optimize the antenna and get better-enhanced results. The antenna is also fabricated and measured results are obtained. The comparison of results shows a good similarity between the simulated and measured results. The designed antenna can be applicable for 5G/ WiFi/WLAN applications.

“…The launch of the sub-6-GHz 5G cell spectrum frequency is based on optimizing the existing 4G technology that the industry has previously created. Sub-6 GHz is a turning point in terms of coverage and penetration, and the 5G experience is vastly different from that of mm-wave [30][31][32][33]. A novel synthesis approach based on mathematical equations is used to determine the physical parameters of DCRFSS-based spatial filters.…”

Frequency selective surfaces (FSSs) play an important role in wireless systems as these can be used as filters, in isolating the unwanted radiation, in microstrip patch antennas for improving the performance of these antennas and in other 5G applications. The analysis and design of the double concentric ring frequency selective surface (DCRFSS) is presented in this research. In the sub-6 GHz 5G FR1 spectrum, a computational synthesis technique for creating DCRFSS based spatial filters is proposed. The analytical tools presented in this study can be used to gain a better understanding of filtering processes and for constructing the spatial filters. Variation of the loop sizes, angles of incidence, and polarization of the concentric rings are the factors which influence the transmission coefficient as per the thorough investigation performed in this paper. A novel synthesis approach based on mathematical equations that may be used to determine the physical parameters of DCRFSSbased spatial filters is presented. The proposed synthesis technique is validated by comparing results from high frequency structure simulator (HFSS), Ansys electronic desktop circuit editor, and an experimental setup. Furthermore, the findings acquired from a unit cell are expanded to a 2 × 2 array, which shows identical performance and therefore proves its stability.

“…Metamaterials are artificially generated electromagnetic structures having properties not seen in natural materials [6]. MTM structures are employed in MTM inspired antennas, filters, sensors, and absorbers for performance enhancement and miniaturization [7][8][9]. Further miniaturization is made possible by making use of ACS feed which reduces the antenna size to almost half of that of coplanar waveguide designs [10].…”

This article presents a novel electrically small asymmetric coplanar strip (ACS) fed metamaterial inspired antenna for quad band operation. A metamaterial inspired open split ring resonator (OSRR) is the radiator which is fed using ACS to obtain four operating bands. The proposed antenna with a compact size of 18 mm × 15.5 mm × 1.6 mm is fabricated and tested. The experimental results are in good compliance with simulated ones. The proposed electrically small antenna has a radian sphere (ka) of 0.65 and achieves an average gain of 2.24 dBi with requisite radiation properties suitable for WiMAX and WLAN applications.
