4E Antenna Technology is the new, sustainable way of achieving conductivity with an accurate and reliable laser process. It is the first feasible alternative to the traditional way of producing antennas by a wet etching process.

The technology brings new dimensions of substrate material choices, exactness, cost efficiency and sustainability to the growing RFID and IoT markets.

THE FOUR Es
1. Ecology
2. Exactness
3. Efficiency
4. Economy

COMPETITIVE ADVANTAGE BY PAPER ANTENNAS
4E Antenna are manufactured using the proprietary laser-based Walki®4E Technology. 4E Antenna enable RFID inlay manufacturers to introduce a game changer product in their product offering. By having inlayless RFID tags based on the paper-based antennas, the RFID inlay manufacturers are able to improve the profitability of their products by lower component costs and improved efficiencies. At the same time, they are able to introduce true sustainability to the RFID market. Pure aluminum layer on the paper substrates of the 4E Antenna enables superior RF-performance compared to current printed antennas. Paper antennas allow eliminating the expensive and non-sustainable etched PET antennas from the manufacturing process. The end result is a sustainable end product with lower total tagging costs.
