Highlights
  • High transparency (>80% open area)
  • Proprietary copper grid conductive layer
  • Implemented in low-profile antennas achieving VSWR, PIM and gain requirements that are typical for non-transparent antennas
  • High power capability (up to 50W)
  • High efficiency (<0.05 ohms per square sheet resistance)
  • Grid performance similar to solid copper
  • High adhesion which allows for small bend radius
  • Darkening treatment for all copper surfaces

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.

Clear and comparable performance

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.
