Product Information

In Fig. 5, parametric analysis is presented to investigate the effect of the square lattice dimensions \('w'\) and \('l'\) of a wired metal mesh on optical transparency, resonance frequency, impedance matching (S11) and isolation (S21). The parametric analysis performance is also summarized in Table 2. The purpose of this analysis is to demonstrate optimization steps for square lattice dimensions of the wired metal mesh to optimize performance of a MIMO antenna with closely spaced antenna elements, while maintaining suitable optical transparency and flexibility.

Transparent Glasses For Men And Women

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.

Achieving optimal performance for multiple parameters simultaneously is a formidable task. Notably, there is still no significant work available in literature that is simultaneously focused to achieve desired optical transparency and flexibility for a MIMO antenna with closely spaced antenna elements. Optimization to achieve required transparency, flexibility, resonance frequency, impedance matching, isolation and radiation performance simultaneously, is a distinct and complex challenge because these performance metrics varies with the variation of the parameters of the square lattice of the wired metal mesh to achieve desired transparency as well.

During the past few years, State-of-the-art flexible and transparent MIMO antennas have been developed using advanced nanotechnology. Researchers have explored various conductive and optically transparent materials, including AgHTs (silver-coated polymers), IZTO (indium zinc thin oxide), ITO (indium tin oxide), and graphene, for their potential use in the development of transparent and flexible antennas for wearable applications. However, AgHTs suffer from high surface resistance and low radiation efficiency for antennas 6 , 7 despite having good flexibility. Furthermore, IZTO and ITO materials are not suitable for future transparent and flexible applications due to their brittleness and high levels of loss when bent, as referenced in 8. Roll-to-roll production of monolayer graphene has been successfully demonstrated, boasting high transparency, electron mobility, and scalability. However, the transfer of large, high-quality graphene films remains a significant challenge, as mentioned in 9 and 10.
