When done, it will let you configure and use this setting for the appearance and performance of Windows on your computer.

The \('w'\) and \('l'\) adjustments also influence the coupling between antenna elements. Sensitivity in \('w'\) and \('l'\) is required to optimize isolation. It can be derived in general from above parametric analysis that the isolation (S21 and S12) between antenna elements decreases with increase in \('w'\) and \('l'\). So, careful fine tuning of these parameters also needed to achieve desired isolation as well as other performance metrics. Figure 7 displays the simulated and measured radiation patterns in both orthogonal planes at 4.5 GHz for one of the elements of the transparent patch antenna.

The use of metallic mesh (MM) has been viewed as a promising technique for transparent and flexible applications owing to its superior transparency, conductivity, and malleability. The full potential of MM structures in contemporary radio frequency devices has not been completely investigated yet. In general, micro-structured MM films have found applications in solar cells, electromagnetic interference shielding 11, and all-solid-state supercapacitors 12. However, there are only a few reported instances of stiff antennas using MMs as conductive electrodes in RF devices. There were reports of low efficiency and poor transparency in these MM antennas, as indicated in 13 and 14. Pradeep, P., Jaya Sankar, K. & Chandra Sekhar, P. A compact semi-circular slot MIMO antenna with enhanced isolation for sub-6 GHz 5g WLAN applications. Wirel. Pers. Commun. 125, 3683–3698 (2022). In addition to the previous analysis, the proposed transparent MIMO antenna is evaluated for its performance using measures such as radiation pattern, Envelope Correlation Coefficient (ECC), Channel Capacity Loss (CCL), Total Active Reflection Coefficient, and Mean Effective Gain (MEG).

For example, startup processes such as driver update apps (e.g. NVIDIA GeForce Experience driver update), welcome screen, hardware companion software, notifications from programs such as Steam client (e.g. when loading for VR headset or running Big Picture Mode), antivirus or anti-malware programs, etc. could appear as a white square box on the screen when it fails to load.

Electronics 11, 251 (2022).Generally, when two antennas are placed in close proximity to each other, these tend to couple or interact with each other, which can lead to poor isolation between the antennas. To overcome this issue, some decoupling structures and techniques are usually employed in literature to achieve better isolation. However, a decoupling structure between antenna elements may cause larger separation between antennas and may also increase power loss, which may limit compactness of MIMO antenna and may also reduce radiation efficiency.

Figure 8 displays the simulated and measured ECC and diversity gain performance of the proposed transparent and flexible MIMO antenna using scattering parameters, which achieves an ECC value lower than 0.005 and corresponding value of 10 for DG in the desired operating frequency band. The ECC is also calculated using far-field patterns and its values are 0.107 at 4.5 GHz while its value is 0.157 and 0.163 at 4.41 and 5.56 GHz, respectively at the center frequency and extreme frequencies of the frequency band for \(-\)10 dB impedance bandwidth. These ECC values are little higher than ECC values calculated through scatting parameters, however, these are still much less than the required minimum value of 0.5 for ECC 17. Total active reflection coefficient (TARC) and channel capacity loss (CCL) A center fed conventional MIMO antenna configuration with same geometrical parameters and spacing between antenna elements as those of the proposed MIMO antenna is also analyzed to verify reason for enhanced isolation due to offset fed configuration and shown in Fig. 3. Scattering parameters for the center fed conventional MIMO antenna are shown in Fig. 4b. It can be seen that the isolation for conventional center fed configuration is only 8 dB. The surface current distribution for conventional center fed MIMO antenna is also shown in Fig. 4a. It can be seen that when antenna-1 is excited and antenna-2 is matched to a 50 \(\Omega \) impedance, a symmetric current distribution is observed on antenna-1 due to center fed excitation. However a significant surface current coupling from antenna-1 to antenna-2 can also be observed, which confirms poor isolation performance for the center-fed configuration. Potti, D. et al.

These can also help to install more antennas in close proximity to enhance signal strength and data speeds 3 for next-generation compact, transparent, and flexible 5G systems. However, a transparent and flexible MIMO antenna configuration is challenging to realize due to complex isolation techniques, such as vias and decoupling structures, which are not ideal for maintaining transparency and low-cost manufacturing processes 4, 5.

In this work, the offset edge fed plays a crucial role in achieving higher isolation between the patch antenna elements and good impedance matching.The fed point for both of the antennas is intentionally shifted or offset from the center of the antenna elements. By optimizing the offset position of the edge fed, higher isolation between the closely spaced patch elements as well as required impedance matching for each antenna and feed line can be achieved.
