Abstract
A radio frequency (RF) antenna containing element is provided. The RF antenna containing element includes a reinforced metal foil laminate antenna bonded to a carrier layer. The reinforced metal foil laminate antenna includes a metal foil layer bonded to a reinforcement layer. The reinforcement layer can mitigate tearing of the metal foil layer during formation of the antenna.
