Transparent antennas are useful for integrating antenna functionality in surfaces while maintaining visibility, such as vehicle windshields and windows. They are designed by META and manufactured using our proprietary NanoWeb® material, a highly transparent metal mesh, which is an improved alternative to Indium tin oxide (ITO). The key benefit of NanoWeb transparent antennas is that high conductivity is maintained without sacrificing the electromagnetic behaviour of the antennas.

NanoWeb Transparent Antenna vs. Identical Metallic
Below are photos of a 5 GHz transparent antenna, along with its measured reflection coefficient compared with an identical metallic version. The graph on the right shows that NanoWeb transparent antenna (blue line) offers very similar performance to an identical conventional metallic version of the same antenna design.
