Abstract
An RFID device for tires utilizes a wireless antenna. The antenna is formed of conductive rubber having a slot formed therein. The conductive rubber antenna is encapsulated between a pair of non-conductive sheets. A third non-conductive member encircles the conductive rubber antenna and is itself sealed between the first and second sheets of non-conductive material. A microchip is positioned in the slot and conductively attached to the antenna on opposite sides of the slot.
