An antenna system and method for tire monitoring systems provides an elasticized substrate in combination with an antenna wire(s). The antenna cable can be wrapped around or otherwise applied to the elasticized substrate, preferably in a wave or sinusoidal configuration. When subjected to forces of external origin, the substrate can elongate while the antenna wire straightens. Upon release from the influence of such forces, residual spring forces within the elasticized substrate relax and return the substrate and the antenna cable carried thereby back to its original, optimal configuration. The pitch of the antenna material on the substrate may be customized to suit the needs of the particular tire and communication. The antenna may be sewn or woven into the elasticized fabric, helically wound around a core composed of such material, or attached in an alternative manner.
