Abstract:
1. A method of making a multilayer, integral, individual planar radio frequency identification element comprising the steps of: providing a first planar substrate sheet having major opposing first and second sides; applying a first one of either a radio frequency identification array antenna and a radio frequency identification array printed circuit chip to the first major side of the first planar substrate sheet; separately applying a second remaining one of the radio frequency identification array antenna and the radio frequency identification array printed circuit chip to the first major side of the first planar substrate sheet in operative overlying relationship and connection with the first one to form an operative radio frequency identification array on the first planar substrate sheet; fixedly and permanently joining a first major outer side of a second planar substrate sheet to the first major side of the first planar substrate sheet overlying the applied antenna and printed circuit chip to form at least part of a multilayer planar core having first and second major outer sides, at least one of the first and second planar substrate sheets being microvoided; fixedly and permanently applying at least a first planar cover sheet to at least the first major outer side of the planar core; and scoring the planar core and at least first planar cover sheet to define at least one multilayer, integral, individual planar radio frequency identification element removable from the core and at least first planar cover sheet, the planar radio frequency identification element containing the operative radio frequency identification array and the planar radio frequency identification element having opposing major planar sides fitting into an area no greater than about three and five-eighths by about two and three-eighths inches.
