Patent ID: 7909955

Claim:
A method of making a multilayer, integral, individual planar radio frequency identification element comprising the steps of: providing a flexible first planar substrate sheet having opposing first and second major sides; applying a first one of either a radio frequency identification array antenna and a radio frequency identification array printed circuit chip to a first portion of the first major side of the first planar substrate sheet; separately applying a remaining second one of the radio frequency identification array antenna and the radio frequency identification array printed circuit chip to the first portion of 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 portion of the first planar substrate sheet; folding a second portion of the first planar substrate sheet over and against the operative radio frequency identification array on the first portion of the first planar substrate sheet so as to completely enclose the radio frequency identification array between the first and second portions; and fixedly and permanently joining together the first and second portions of the first major side of the first planar substrate sheet enclosing the applied antenna and printed circuit chip operative radio frequency identification array to encapsulate the applied antenna and printed circuit chip operative radio frequency identification array and form at least part of a multilayer planar core having first and second major outer sides; scoring at least the planar core to define at least one multilayer, integral, individual planar radio frequency identification element removable from the planar core containing the operative radio frequency identification array.
