Most wireless data originates or terminates indoors. From restaurants to lobbies, stadiums to offices, antennas that blend in with their surroundings can help enable high-speed 5G networking.
3M™ Transparent Conductor Film Assembly is a thin, transparent conductive film that has a custom copper grid pattern as the conductive layer. It can be laminated to a rigid transparent polycarbonate support to help enable wireless sub-6GHz antennas for indoor and outdoor settings. An innovative conductive transparent film, it uses a proprietary copper grid conductive layer to enable inconspicuous, high-power antenna designs with low surface electrical resistance.
In lab and real-world tests versus a solid-plated-copper reference antenna, antennas using 3M™ Transparent Conductor Film demonstrated strong performance across a range of frequency bands. Contact 3M for detailed testing data.
Return loss testing found that antennas built with 3M™ Transparent Conductor Film had very similar return loss performance to solid-copper-plated antennas.
Antenna performance using 3M™ Transparent Conductor Film was compared with copper across the 2.4GHz, 5GHz and 6GHz frequency bands. Across 23 test sites at a range of distances and line-of-sight conditions, the antenna demonstrated comparable signal strength.
