“…The decoupling network was reported in [16,17]. In addition, several studies on metasurfaces have been reported in [18][19][20]. The content of these researches can only improve the coupling of single frequency point or narrow band, which can not provide good universality for the design of broadband MIMO antenna.…”

A compact 4-port coplanar waveguide (CPW) fed ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with enhanced isolation is proposed to operate from 3.66 GHz to 16.61 GHz with 127.78 % impedance bandwidth. The proposed antenna system consists of four orthogonal arrays of monopole antennas improved by four iterations.The UWB characteristic of the antenna is obtained from an improved monopole antenna fed by CPW. The final MIMO antenna is printed on a Rogers 4003C substrate with dimensions of 60 × 60 × 0.3 mm3.The orthogonal arrangement of antennas brings about the polarization diversity and certain isolation of MIMO antennas.Four rows of orthogonal metasurface elements with via holes and the ring of the backplane further improve the isolation between antenna elements in the MIMO system. The measured results of MIMO antenna agree with the simulated results. The MIMO antenna achieves an impedance bandwidth of 12.95 GHz with S11 < -10 dB and good isolation ( S21 = S41 < -30 dB and S31 < -20 dB). In particular, S31 is always less than -25 dB at frequencies greater than 6 GHz. The optimized MIMO antenna has the advantages of UWB, compact size, good radiation, and enhanced isolation, which shows that it has potential application value in UWB wireless communication systems.

“…A lot of research is being carried out in controlling antenna radiation pattern (beam steering) through means like photons (1) , and multi-directional beaming is also obtained by using metasurface antennas (2) .Other antenna parameters like bandwidth are gain are being enhanced using AIRP-m metasurfaces (3) . Designs of MIMO antennas are optimized for higher bandwidths for 6G communications (4) and isolation is achieved using metasurfaces (5) . The metasurface material is yet another area where a lot of experimentation is performed, textile based wearable antenna designs are being explored for body area networks (6) .…”

Objectives: To design a metasurface layer of graphene unit cells with reduced surface area by incorporating different geometry of unit cell. Methods: The metasurface layer in the form of unit cell array is traditionally made of very simple geometry like square unit cell to limit design complexity. However, if the unit cell structure geometry is changed to triangular shape, it reduces the total surface area of the metasurface layer, thereby saving the graphene material. The proposed design is not only reduces the size of the metasurface layer of THz antenna but also enhances the performance of the antenna. Findings: The single square unit cell structure has 337.46 µm 2 area and an array of 9 x 9 such unit cells consume 27334.26 µm 2 area. On the other hand, a single triangular unit cell design is 123.94 µm 2 and an array of 9 x 9 such unit cells consume only 10039.14 µm 2 area which is a saving of 63.35 % metasurface material. Novelty:The proposed antenna design in the paper compares the existing designs for better bandwidth, better return loss and reduction in the total surface area utilized by the metasurface layer and delivers a better performance.
