Transparent Antennas

Transparent antennas are useful for integrating antenna functionality in surfaces while maintaining visibility, such as vehicle windshields and windows. They are designed by MTI 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
A monopole 5 GHz transparent antenna, along with measured reﬂection coefﬁcient compared with an identical metallic version. The Nanoweb transparent antenna (blue line) offers very similar performance to an identical conventional metallic version of the
same antenna design.
