Embodiment Construction

[0021] see figure 1 , a conventional passive microwave RFID tag 1 is used here to illustrate the present invention. The microwave RFID tag 1 includes a microwave RFID chip 2 and a dipole antenna 4 mounted on a non-conductive polymer substrate 6 . If the microwave RFID tag 1 is made active, a battery will be added as an additional component of the tag. However, the battery will affect the operation of the antenna 4, and the battery needs to be placed at a certain distance from the antenna 4, resulting in a larger tag. Conventional active tags are typically stiff or inflexible due to the mounting requirement that the battery be separated from the antenna.

[0022] see figure 2 , an active microwave RFID tag 10, as further described below, provides a form of figure 1 The thin-film battery 8 of the dipole antenna 4 is shown in . Since the battery and antenna are formed as a co-located structure, the substrate 6 can be made relatively more flexible than conventional active RF...

Abstract

An active RFID label is provided in which the antenna also forms the battery for the RFID chip that is part of the label. The antenna can be made of one or both of the electrodes forming a thin-film lithium-ion battery. The RFID chip, antenna and battery can all be placed upon the same substrate, and because the antenna and battery are co-located, the substrate can be made relatively flexible.

Description

technical field [0001] The present invention relates to radio frequency identification (RFID) tags and, more particularly, to active RFID tags including a battery and an antenna as integral components. Background technique [0002] Objects associated with inventory, product manufacturing, merchandising planning, and related operations create challenges for accurately monitoring object location and flow. There is a continuing need to determine the location of these objects and track information about these objects. A tagging device may be used that is suitably configured to be associated with a variety of objects, including goods, items, people or animals, or virtually any object, moving or stationary and animate or inanimate. One such tag tracking system is an electronic identification system, such as RFID. In order to track objects and store and retrieve information about the objects, RFID tags are attached, connected or otherwise associated with the objects. [0003] In...
