About this deal

Have you encountered the transparent or translucent box on the Windows screen when you are using Windows 11? If the transparent or translucent box problem occurs frequently, our guess is that there is some problem with your graphics driver or other reasons. You can reinstall Display adapters to fix transparent or translucent box on screen in Windows 11. Here is the guide: 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.

The detailed steps are as follows.

Multi-input-multi-output (MIMO) antenna systems are used to enhance spectral efficiency and channel capacities of 5G and IoT infrastructure 1, 2. Transparent and flexible MIMO antennas serve as a key element to maintain compatibility with devices of varying shapes and sizes while minimizing their visual impact. The optical transparency may help to increase visual aesthetics of 5G-enabled base stations, smartphones, tablets and wide range of IoT devices, from environmental sensors to home automation devices. While the flexibility of the antenna design might make it suitable for integration into flexible communication modules or boards that can be adapted to various types of IoT sensor nodes and devices with different form factor. Our square clear plastic tubes are also available as a Sealed Bottom Clear Plastic Square Tube where a clear bottom is permanently adhered into the tube.Hashiba, J., Kawajiri, T., Shibuya, R. & Ishikuro, H.

Step 2: Select the Personalize option from the left panel, and then switch to the right and expand the Taskbar. There are 4 applicable ways to fix the transparent or translucent box on screen in Windows 11. Way 1: Restart Graphics Driver When you export your image, it will be processed as a PNG which you can save directly to your device or share on social media! This image file will have fully or partially transparent sections that you removed in the Studio, so it's ready to overlay on other images or videos or use as a custom emoji in platforms that use them.

Equation ( 1) reveals that O.T of a transparent antenna can be enhanced by increasing \('l'\) and decreasing \('w'\) due to decrease in coverage of copper, which may reduce radiation performance of antenna. So, balancing \('w'\) and \('l'\) to maximize O.T without sacrificing overall MIMO antenna performance with closely spaced antenna elements is a challenging task. Resonance frequencyA 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. 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) 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. Desai, A., Palandoken, M., Kulkarni, J., Byun, G. & Nguyen, T. K.
