Abstract
An RFID tag for marking storm drains incorporates the tag circuitry into a dome decal providing a flexible substrate capped by a self-leveling clear polymer. The RFID tag is placed between the polymer and the substrate on an electromagnetic radiation decoupling layer allowing a low profile fitting within the decal while allowing the decal to be used on metal drain surfaces. The decal includes a printed environment-promoting message relating to connection of the storm
Claims19
A dome decal RFID marker comprising:
- a flexible polymer substrate having a lower planar surface suitable for attachment by an adhesive to a planar surface of a storm drain;
- an electromagnetic radiation decoupling layer attached to an upper planar surface of the flexible polymer substrate;
- an RFID tag attached to an upper surface of the electromagnetic radiation decoupling layer at a location of enhanced electromagnetic field when an electromagnetic field is directed downward toward the dome decal RFID marker;
- and
- a polyurethane protective layer sealing the RFID tag and the electromagnetic radiation decoupling layer to the flexible polymer substrate through viscous flow of the polyurethane protective layer prior to hardening.
