“…The following table shows some literature about Sub-6G antenna in recent years. In these references, 1,3,[18][19][20][21][22][23][24] all designed antennas work at Sub-6GHz band, and antennas of references [18][19][20] belong to multi-band MIMO antennas. Antennas of references 1,3,[21][22][23][24] are wideband MIMO antennas, antennas of references 1,21 are only two-port MIMO antennas, and other antennas of references 3,23,24 are four-port MIMO antennas without connected ground.…”

Aiming at the application of Sub‐6 GHz band, this paper presents a high isolation four‐port MIMO slot antenna with CPW feeding mode. About this antenna, two parallel binary antennas are oppositely arranged with connected ground, and isolation branches are adopted to improve isolation. Each element antenna is realized through elliptical shape patch and trident structure feed line. The measured results show that its working frequency band is 1.82–6.5 GHz band, with ports isolation less than −20 dB. In addition, its other performance parameters are good, such as gain of 7.03 dB and ECC parameter below 0.004, and CCL is less than 0.3 bps/Hz. The antenna has high isolation and it can not only work in the mobile communication frequency bands such as n41, n77, n78, and n79, but also work in the frequency band of the IoT, such as WiFi5, V2X, and DSRC.

“…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.

“…Using a neutralization line can reduce the mutual coupling in the antenna structure by using meander microstrip lines. It provides fexibility for the antenna [17]. For achieving better MIMO characteristics like broader bandwidth and higher isolation in an antenna, the authors use a ring resonatorbased coplanar waveguide to feed the ports [18].…”

New frequencies can be supported with very effective space use by using the shared aperture antenna This work presents on designing a dual-banddual-polarized (DBDP) S/X-band shared aperture antenna (SAA) for synthetic aperture radar (SAR) applications operating at S-band frequency (3.2 GHz) and X-band frequency (9.65 GHz). The single-layer SAA DBDP S-band antenna is designed in a square-shaped patch with coaxial feeding in both vertical and horizontal polarization. The X-band antenna design is in 1 × 3 vertical series with microstrip feeding and arranged at four corners of the proposed antenna. The S-band antenna is mainly used for airborne applications such as air traffic control and surface ship radar. In contrast, the X-band antenna application is maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement. To verify the antenna, a prototype is fabricated and measured with s-parameters. The proposed design exhibits that the gain of the S-band is 7.2 dB and for the X-band is 12.4 dB, and the isolation is achieved more than −35 dB, and for this antenna, we achieved a bandwidth of 0.12 GHz for S-band and 0.27 GHz for X-band. However, the X-band antenna is a multi-input and multioutput antenna that is to be validated by using MIMO characteristic parameters such as envelope correlation coefficient (ECC), diversity gain (DG), channel capacity loss (CCL), mean effective gain, and mutual coupling. The MIMO characteristic parameter of X-band antenna values is found to be in a similar manner to both simulated and measured values. For this X-Band antenna, ECC, DG, CCL, and mutual coupling were achieved as below 0.05, 9.5 dB, 0.5 bps/Hz, and −30 dB to −55 dB, respectively. The total size of the antenna is 100 mm × 100 mm × 1.6 mm.
