Title: Radio Frequency Identification (RFID) Tags for Metallic and Three-Dimensional (3D) Objects and Methods of Making and Using Thereof

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority to and the benefit of U.S. provisional utility patent application Nos. 62/854,126 filed May 29, 2019 and 62/954,482 filed Dec. 28, 2019, each of which is incorporated herein by reference in its entirety. 
    
    
     FIELD 
     The present invention relates generally to (1) the production of a radio frequency identification (RFID) tags that can be generated on three dimensional (3D) objects or packages and (2) the production of a reactive radio frequency identification (RFID) strap which interacts with a metallic object and induces current flow in it. More specifically, for 3D objects, the RFID tag can be formed on the surface of the 3D object or its primary or secondary packaging by producing a conductive material on the object, compensating for its shape and position, and coupling the conductive material to a reactive RFID strap to form the RFID tag that can then induce a far field RFID antenna response. For metallic objects, the reactive RFID strap can be secured to a plastic clip for relatively easy attachment to the metallic object; and if the size and shape of the metallic object are suitable, the reactive RFID strap can induce a far field RFID antenna response. 
     BACKGROUND 
     Generally stated, radio-frequency identification is the use of electromagnetic energy to stimulate a responsive device (known as an RFID “tag” or transponder) to identify itself and, in some cases, provide additional information and/or data stored in the tag. RFID tags typically comprise a semiconductor device commonly referred to as the “chip”, upon which are formed a memory and an operating circuitry, which is connected to an antenna. Typically, RFID tags act as transponders, providing information stored in the chip memory in response to a radio frequency interrogation signal received from a reader, also referred to as an interrogator. In the case of passive RFID devices, the energy of the interrogation signal also provides the necessary energy to operate the RFID tag device. 
     As referenced above, RFID tags are generally formed by connecting an RFID chip to some form of antenna. Antenna types are very diverse, as are the methods of constructing the same. One particularly advantageous method of making RFID tags is to use a strap, a small device with an RFID chip connected to two or more conductors that can be coupled to an antenna. The coupling of the conductors to the antenna can be achieved using a conductive connection, an electric field connection, magnetic connection or a combination of coupling methods. 
     RFID tags may be incorporated into or attached to articles that a user wishes to later identify and/or track. In some cases, the tag may be attached to the outside of the article with a clip, adhesive, tape, or other means and, in other cases, the RFID tag may be inserted within the article, such as being included in the packaging, located within the container of the article, or sewn into a garment. Further, RFID tags are manufactured with a unique identification number which is typically a simple serial number of a few bytes with a check digit attached. This identification number is typically incorporated into the RFID tag during its manufacture. The user cannot alter this serial/identification number, and manufacturers guarantee that each RFID tag serial number is used only once and is, therefore, unique. Such read-only RFID tags typically are permanently attached to an article to be identified and/or tracked and, once attached, the serial number of the tag is associated with its host article in a computer database. 
     Frequently, a number of retail and other items are metallic in some form. These metallic retail items typically require an RFID tag or strap to be attached to them in order to track the item. However, it is sometimes necessary for these RFID tags or straps also to be removable and/or only be active for a limited distance. Therefore, there exists in the art a long felt need to manufacture a reactive RFID strap that can be removably secured to a metallic item. There also exists in the art a long felt need for a reactive RFID strap that induces a current to flow in the metallic object. In one embodiment, the present invention discloses a reactive RFID strap that can be secured to a plastic clip for easy attachment to a metallic object; and if the size and shape of the metallic object are suitable, the reactive RFID strap can induce a far field RFID antenna response. 
     Additionally, a number of retail products, other items, and their associated packaging have non-planar surfaces that are not ideal for receiving traditional RFID tags thereon. For example, on a bottle, it is oftentimes necessary to form the RFID tag antenna on the flat portion of the base or top of the bottle to obtain a more secure attachment between the bottle and the RFID tag, as opposed to a curved portion of said bottle. Therefore, there also exists in the art a long felt need for a method of forming an antenna on any portion of the bottle, or any other non-planar surface, that is adapted to the shape that, when used in conjunction with a reactive RFID strap that is flexible enough to conform to the surface, a high performance RFID tag is created. More specifically, the present invention discloses a method of depositing a conductor onto a non-planar surface of an object, wherein the antenna shape may be adapted to function optimally and thereby providing the manufacturer with greater flexibility in RFID tag formation and/or placement. 
     SUMMARY 
     The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later. 
     RFID tags for metallic objects and three dimensional (3D) objects are described herein. For metallic objects, in some embodiments, the tags contain reactive RFID strap components containing an RFID chip or strap and a conductor component which are both secured to a plastic clip component. The reactive RFID strap component is then attached to a metallic item or object. If the size and shape of the metallic item is suitable, the reactive RFID strap component can induce a far field antenna response, wherein coupling can be between electric fields, magnetic fields, or both with coupling related to the structure of the reactive RFID strap component and its proximity to the metallic item. 
     The clip component of the reactive RFID strap component may be provided in multiple forms. In some embodiments, the tab of a clip component may contain an edge that is aligned with an outside edge of a frame section. In other embodiments, the tab of the clip component can be surrounded or encircled by the frame section on all edges or sides. Nonetheless, as explained more fully below, these two examples of possible types of clip components provide different mechanical properties. For example, the first example offered above is easier to fit and easier to position over an edge of a metallic item, but it is not as robust as the second example. On the other hand, while the second example of a possible clip style may be harder to attach to the metallic object, it is more robust than the first example and will likely have a longer useful life. 
     The reactive RFID strap component can be secured to the clip component in multiple ways. In some embodiments, the conductor component can be formed in a conductive loop with the RFID chip in series, coupling primarily by the magnetic fields. In other embodiments, the conductive component can be a generally U-shaped conductor on the frame which couples to a metallic item primarily by the electric fields. In still other embodiments, the conductive component can be a conductive loop that is mounted on the frame and runs around or encircles the tab of the clip component. 
     Methods of manufacturing the reactive RFID strap component for metallic objects are also disclosed. The method generally includes forming an antenna on the surface of a suitable substrate. The substrate can be formed of any suitable material. Exemplary materials include, but are not limited to, plastic. An RFID chip or strap is then attached, and the clip component cut. The clip component may be retained in the web by a series of tabs or be positioned on a release liner and attached by an adhesive. The clip components are then formatted for use, for example, by placing them in rolls, canisters, or bags. The clip components can also be modified to help secure the clip component to the metallic item by adding surface deflections, adhesive fixing points, or tabs designed to engage with an existing hole or opening in the metallic item package or object thereby forming a more secure connection between the clip component and the metallic item. 
     In some embodiments, the RFID tag is formed on the surface of a 3D object or its primary or secondary packaging. In some embodiments, the RFID tag is formed by producing a conductive material on the object, compensating for its shape and position, and coupling the conductive material to a reactive RFID strap to form the RFID tag that can then induce a far field RFID antenna response. The RFID tag device is particularly suited for non-planar objects, and gives greater choice on packaging where the RFID tag must be formed and an antenna shape must be adapted to conform to the packaging&#39;s geometry to optimally function. 
     In some embodiments, a reactive RFID strap component contains an RFID chip or strap and a conductor component which are both secured to a plastic clip component. The reactive RFID strap component is then attached to the 3D object. If the size and shape of the 3D object is suitable, the reactive RFID strap component can induce a far field antenna response, wherein coupling can be between electric fields, magnetic fields, or both with coupling related to the structure of the reactive RFID strap component and its proximity to the 3D item. 
     The clip component of the reactive RFID strap component may be provided in multiple forms. For example, the tab of a clip component may contain an edge that is aligned with an outside edge of a frame section. Alternatively, the tab of the clip component can be surrounded or encircled by the frame section on all edges or sides. Nonetheless, as explained more fully below, these two examples of possible types of clip components provide different mechanical properties. For example, the first example offered above is easier to fit and easier to position over an edge of a 3D object, but it is not as robust as the second example. On the other hand, while the second example of a possible clip style may be harder to attach to the 3D object, it is more robust than the first example and will likely have a longer useful life. 
     Furthermore, the reactive RFID strap component can be secured to the clip component in multiple ways. For example, the conductor component can be formed in a conductive loop with the RFID chip in series, coupling primarily by the magnetic fields. Alternatively, the conductive component can be a generally U-shaped conductor on the frame which couples to a metallic item primarily by the electric fields. In a further alternative embodiment, the conductive component can be a conductive loop that is mounted on the frame and runs around or encircles the tab of the clip component. 
     A method of manufacturing the reactive RFID strap component is also disclosed. The method generally comprises forming an antenna on the surface of a suitable material, such as plastic. A RFID chip or strap is then attached, and the clip component cut. The clip component may be retained in the web by a series of tabs or be positioned on a release liner and attached by an adhesive. The clip components are then formatted for use, such as by placing them in rolls, canisters, or bags. The clip components can also be modified to help secure the clip component to the metallic item by adding surface deflections, adhesive fixing points, or tabs designed to engage with an existing hole or opening in the 3D item package or object thereby forming a more secure connection between the clip component and the 3D object. 
     In other embodiments, the method includes forming an antenna on the surface of the non-planar object, and positioning a reactive RFID strap on the surface of the non-planar object near the antenna to form the RFID tag. The reactive RFID strap is coupled to the antenna so that a far field antenna response is induced, wherein coupling can be between electric fields, magnetic fields, or both. 
     In other embodiments, the reactive RFID strap may be positioned before the antenna is formed on the surface of the non-planar object. The antenna may be manufactured from a conductive liquid and may be either sprayed or printed onto the surface of the non-planar object by ink jet spraying or printing. Alternatively, the antenna may be manufactured from a metal foil and positioned on the surface of the non-planar object. Further, if the surface area of the non-planar object is overly complex (e.g., contoured) at the location where the RFID antenna is formed, the method may further comprise adding a physical connection between the RFID antenna and the reactive RFID tag. 
     In some embodiments, a method of manufacturing a RFID tag adapted for a non-planar object is disclosed. The method preferably includes scanning a surface of the non-planar object and then selecting a suitable design for an RFID antenna at a chosen location on the surface of the non-planar object. A suitable design for a reactive RFID strap may then be selected along with a suitable position for positioning the reactive RFID strap relative to the non-planar object, and the RFID tag can then be formed on the surface of the on-planar object. More specifically, the RFID antenna may be formed on the surface of the non-planar object either before or after the reactive RFID strap is positioned on the surface. Additionally, a radio frequency (RF) performance may be measured to ensure proper performance of the RFID tag and for purposes of optimizing the design. The reactive RFID strap is coupled to the antenna so that a far field antenna response is induced, wherein coupling can be between electric fields, magnetic fields, or both. 
     In still other embodiments, the method of manufacturing a RFID tag adapted for a non-planar object includes first depositing a separator on a surface of a non-planar object. An antenna is then formed on the separator, and a reactive RFID strap is positioned on the separator so that the reactive RFID strap couples with the antenna to form the RFID tag. The reactive RFID strap is coupled to the antenna so that a far field antenna response is induced, wherein coupling can be between electric fields, magnetic fields, or both. The separator may be measured for thickness, and the separator thickness adapted to ensure stability of the RFID tag. The separator may further comprise a ramped portion so that the antenna may be formed on the separator, down the ramped portion, and into contact with the surface of the non-planar object. Alternatively, a base conductor may be first positioned on the surface of the non-planar object, and the separator may be deposited or positioned atop the base conductor. 
     To the accomplishment of the foregoing and related ends, certain illustrative aspects of the disclosed innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles disclosed herein can be employed and is intended to include all such aspects and their equivalents. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.

     DETAILED DESCRIPTION 
     The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. 
     I. RFID Tags 
     A. Metallic Items or Objects 
     In one embodiment, the reactive RFID strap components contain an RFID chip or strap and a conductor component which are both secured to a clip component, such as a clip component formed of plastic or some other suitable material. The reactive RFID strap component is then attached to a metallic item or object. If the size and shape of the metallic item is suitable, the reactive RFID strap component is capable of inducing a far field antenna response, wherein coupling can be between electric fields, magnetic fields, or both with the coupling related to the structure of the reactive RFID strap component and its proximity to the metallic item. 
     In some embodiments, the RFID chip and conductor component can be secured to the clip component in multiple ways. For example, the conductor component can be formed in a conductive loop with the RFID chip in series, with coupling primarily by the magnetic fields. Alternatively, the conductor component can be a generally U-shaped conductor on the frame which couples to a metallic item primarily by the electric fields. In other embodiments, the conductor component can be a conductive loop that is mounted on the frame and encircles the tab of the clip component. The various alternative embodiments of the clip components can be modified to help secure the clip component to the metallic item by adding surface deflections, adhesive fixing points, or tabs designed to engage with an opening or plurality of openings already formed in the metallic item or package to provide a more secure attachment thereto. Furthermore, various methods of manufacturing a RFID tag comprising an antenna and a reactive RFID strap on a three dimensional (3D) or non-planar object are also disclosed. 
     Referring initially to the drawings,  FIG. 1  illustrates a top perspective view of a reactive RFID strap component  100  in proximity with and coupled to a metallic item  108  or other conductive object. The reactive RFID strap component  100  is typically a reactive strap which induces an antenna response into the metallic item  108 , and is integrated into a plastic clip but can be any reactive object as is known in the art. Further, reactive RFID strap component  100  can be any suitable size, shape, and/or configuration as is known in the art without affecting the overall concept of the invention. One of ordinary skill in the art will appreciate that the shape, size and configuration of the reactive RFID strap component  100  shown in the various FIGS. is for illustrative purposes only, and that many other shapes and sizes of the reactive RFID strap component  100  are well within the scope of the present disclosure. Although the dimensions of the reactive RFID strap component  100  (i.e., length, width, and height) are important design parameters for good performance, the reactive RFID strap component  100  may be any shape, size or configuration that ensures optimal performance during use and satisfies user need or preference. 
     Typically, the reactive RFID strap component  100  is comprised of a RFID chip or strap  102  and a conductor component  104  which are both secured to a clip component  106 . The reactive RFID strap component  100  is then attached to a metallic item  108  or other suitable conductive object as is known in the art. If the size and shape of the metallic item  108  are sufficient, the reactive RFID strap component  100  can induce a far field antenna response. For example, coupling can be via electric fields (E), magnetic fields (H), or commonly, by both electric (E) and magnetic (H) fields with coupling being related to the structure of the reactive RFID strap component  100  and its proximity to the metallic item  108 . Thus, coupling of the reactive RFID strap component  100  to the metallic item  108  in the electric (E) and magnetic (H) fields is somewhat dependent upon geometry. 
     The reactive RFID strap components  100  can be versatile, such that they can be altered depending on the needs and/or wants of a user. For example, the reactive RFID strap components  100  can be produced to be relatively flat so they can be used in a roll to roll process, or other suitable distribution process as is known in the art. Further, the reactive RFID strap components  100  are designed to slip over the edges of metallic items  108  and could incorporate a stop such that they only transmit a certain distance. Additionally, the reactive RFID strap components  100  of the present invention in their various possible alternative embodiments can comprise an adhesive with a release liner making the reactive RFID strap components  100  easy to attach to and remove from the metallic items  108 . The profile of the strap component  100 , or the amount of material that sticks up above the metallic item  108 , can be varied as well, depending on the needs and/or wants of a user. Overall, the reactive RFID strap components  100  are produced to be quite robust or strong and easily applied to the metallic items  108 . 
     As shown in  FIGS. 2A-B , the RFID chip  102  and the conductor component  104  may both be secured to a clip component  106 . More specifically,  FIG. 2A  illustrates a front perspective view of one possible embodiment of the clip component  106 , and  FIG. 2B  illustrates a front perspective view of an alternative embodiment of the clip component. Typically, the clip component  106  is a plastic clip, but can also be made of any suitable material as is known in the art. Further, the clip component  106  can be any suitable size, shape, and/or configuration as is known in the art without affecting the overall concept of the invention. One of ordinary skill in the art will appreciate that the shape, size and configuration of the clip component  106  shown in  FIGS. 2A-B  is for illustrative purposes only, and that many other shapes and sizes of the clip component  106  are well within the scope of the present disclosure. Although the dimensions of the clip component  106  (i.e., length, width, and height) are important design parameters for good performance, the clip component  106  may be any shape or size that ensures optimal performance during use. Further, the clip component  106  can typically be utilized in two basic forms as shown, however the clip component  106  can also utilize other suitable forms as is known in the art. 
     As shown in  FIG. 2A , the clip component  106  comprises a tab component  200  and a frame component  202 . The tab component  200  comprises an edge section  204  that is aligned with the outside edge section  206  of the frame component  202 . As shown in  FIG. 2B , the clip component  106  comprises the tab component  200  surrounded by the frame component  202  on all edges. Thus, the two different forms of clip components  106  comprise different mechanical properties. For example, the clip component  106  of  FIG. 2A  would be easier to fit to a metallic item  108 , as at the end of the manufacturing process, the tab component  200  can be deflected and can easily be pushed over the aligned edge sections  204  and  206 . However, the clip component  106  form of  FIG. 2A  is less robust than that shown in  FIG. 2B . Conversely, while the form of clip component  106  of  FIG. 2B  is more difficult to attach to a metallic item or object  108  compared to the form of clip component shown in  FIG. 2A , the clip component form of  FIG. 2B  is more robust than the clip component form disclosed in  FIG. 2A  and will typically have a longer useful life. 
     As shown in  FIGS. 3A-C , the RFID chip  102  and the conductor component  104  are both secured to a clip component  106 . The RFID chip  102  and the conductor component  104  can be secured to the clip component  106  in multiple ways depending on the wants and/or needs of a user such as, for example, with adhesives. Further, the conductor component  104  can be any suitable size, shape, and/or configuration as is known in the art without affecting the overall concept of the invention. One of ordinary skill in the art will appreciate that the shape, size and configuration of the conductor component  104  shown in  FIGS. 3A-C  is for illustrative purposes only, and that many other shapes and sizes of the conductor component  104  are well within the scope of the present disclosure. Although the dimensions of the conductor component  104  (i.e., length, width, and height) are important design parameters for good performance, the conductor component  104  may be any shape or size that ensures optimal performance during use and that satisfies user need. 
     Further, the conductor component  104  can typically be fitted to the clip component  106  in a multitude of different ways such as those shown, for example, in  FIGS. 3A-C . However, the conductor component  104  can also be fitted to the clip component  106  in any other suitable way as is known in the art. As shown in  FIG. 3A , the conductor component  104  can be positioned in a conductive loop with the RFID chip  102  in series, thus coupling primarily in the magnetic (H) fields and positioned on the tab component  200 . Alternatively, as shown in  FIG. 3B , the conductor component  104  can be formed as a generally U-shaped conductor on the frame component  202 , which couples to the metallic item  108  primarily by electric (E) field coupling. In a further alternative embodiment shown in  FIG. 3C , the conductor component  104  may be positioned in a conductive loop with the RFID chip  102  in series and mounted on the frame component  202  such that it encircles the tab component  200 . 
       FIG. 4  illustrates a flowchart of a basic method of manufacturing a reactive RFID strap component  100  for use with a metallic item  108 . At  400 , the method comprises forming an antenna on the surface of a suitable material, such as plastic, for example, polyethylene terephthalate (PET). Ideally, the material is thick enough to be self-supporting as a clip component, but thin enough to be processed roll to roll, for example 0.5 mm thick, or any other suitable thickness as is known in the art. Alternatively, a thick card or corrugated material may be used, or any other suitable material as is known in the art, if the roll to roll process is not used. Specifically, the antenna may be formed via pattern printing an adhesive, laminating the foil, cutting around the pattern, and stripping the matrix. 
     At  402 , a RFID chip or strap is then attached to the antenna, and at  404  the clip component is die cut such that a user cuts around the critical structural elements. The clip component may be retained in the web by a series of tabs or be positioned on a release liner and attached by an adhesive. At  406 , the clip components may then be formatted for use, such as by placing the clip components in rolls, canisters, or bags. For example, at  408 , the clip components can be formatted in rolls, the rolls are then used in a printer and dispensed into a product. At  410 , the clip components are cut into single units and dropped into a bag for manual assembly. At  412 , the clip components are stacked into a tube or canister for use with an applicator gun. 
     As shown in  FIGS. 5A-B , the reactive RFID strap component  100  may be modified via tools that apply heat and/or pressure to create deflections  500 . Alternatively, other suitable tools known in the art for making deflections  500  may be used, for example, punches. More specifically,  FIGS. 5A-B  illustrate front and side views of the reactive RFID strap component  100  before being shaped by the heat and/or pressure tool, or an alternative tool, to create deflections  500 . 
     Conversely,  FIGS. 5B-C  illustrate front and side views of the reactive RFID strap component  100  post-deflection creating process, namely after being shaped by a tool that uses heat and/or pressure, or other means, to form deflections  500  therein. The deflections  500  can either be 3D raised bump structures  502  or lowered bump structures  504  on the surface of the reactive RFID strap component  100 . The deflections  500  comprise surface bumps or catches which help to attach the clip component  106  to the conductor component  104  in a secure manner. 
     As shown in  FIGS. 6A-B , the reactive RFID strap component  100  can further comprise additional grip  600  or adhesive fixing points  602  to better secure the clip component  106 . More specifically,  FIG. 6A  illustrates a front perspective view of an embodiment of the reactive RFID strap component  100  modified with additional adhesive grips  600  and adhesive fixing points  602 , and FIG.  6 B illustrates a front perspective view of an alternative embodiment of the reactive RFID strap component  100  modified with additional grips  600  and adhesive fixing points  602 . Additional grips  600  and/or adhesive fixing points  602  may be added by printing or any other suitable form of dispensing as is known in the art. The grip  600  and adhesive fixing points  602  are typically added to the surface of the reactive RFID strap component  100 , but may also be added to any other suitable area as is known in the art. 
     Additionally, as shown in  FIGS. 7A-C , the reactive RFID strap component  100  may further comprise a plurality of tabs  700  formed on its surface. As shown in  FIG. 7A , any number of tabs  700  can be used depending on the wants and/or needs of a particular user. Specifically, the tabs  700  can be non-return flaps that are pushed out of the reactive RFID strap component  100  (see  FIG. 7B ). As shown in  FIG. 7C , the tabs  700  engage the metallic item  108 . Typically, the tabs  700  engage a hole or opening  702  positioned in the metallic item  108 , or any other suitable area of the metallic item  108  as is known in the art. The hole or opening  702  is typically the opening already formed in the metallic item or object  108  and that is used for hanging the item  108  on a display rail or hook. 
     As shown in  FIG. 8 , the reactive RFID strap component  100  may be secured to a metallic bag  800  to induce a far field antenna response, wherein coupling can be between electric fields, magnetic fields, or both. Further,  FIG. 9  illustrates a graph of the far field response in accordance with the disclosed architecture, and which illustrates an approximate −11 dBm sensitivity over the FCC band. 
     As shown in  FIG. 10 , the reactive RFID strap component  100  may also be secured to a metallic box  902  to induce a far field antenna response, wherein coupling can be between electric fields, magnetic fields, or both. Further,  FIG. 11  illustrates a graph of the far field response in accordance with the disclosed architecture, and which illustrates an approximate −10 dBm sensitivity over the FCC band. 
     B. Three-Dimensional (3D) Objects 
       FIGS. 12-14  illustrate a, RFID tag  1000  positioned on a surface  1052  of a non-planar object  1050 , and a method of manufacturing the same. The RFID tag  1000  contains an antenna  1002  and a reactive RFID strap  1004 . The reactive RFID strap  1004  further contains an RFID chip  1006 . Both the antenna  1002  and the reactive RFID strap  1004  can be any suitable size, shape, and/or configuration as is known in the art without affecting the overall concept of the invention. One of ordinary skill in the art will appreciate that the shape, size and configuration of both the antenna  1002  and the reactive RFID strap  1004  shown in the various FIGS. are for illustrative purposes only, and that many other shapes and sizes of both the antenna  1002  and the reactive RFID strap  1004  are well within the scope of the present disclosure. Although the dimensions of both the antenna  1002  and the reactive RFID strap  1004  (i.e., length, width, and height) are important design parameters for good performance, both the antenna  1002  and the reactive RFID strap  1004  may be any shape, size or configuration that ensures optimal performance during use and satisfies user need and/or preference. 
     Typically, the RFID tag  1000  can induce a far field antenna response. For example, coupling of the antenna  1002  to the reactive RFID strap  1004  can be via electric fields (E), magnetic fields (H), or commonly, by both electric (E) and magnetic (H) fields with coupling being related to the structure of the RFID tag  1000 . Therefore, coupling of the antenna  1002  to the reactive RFID strap  1004  in the electric (E) and magnetic (H) fields is somewhat dependent upon geometry. The antenna  1002  is conductive and is typically formed from a variety of conductive materials, such as, but not limited to, metal foils, cut mechanically or by a laser, printed conductive inks, or vapor deposited materials. Furthermore, the RFID tag  100  is formed by positioning the antenna  1002  near the reactive RFID strap  1004 . 
     The generally non-planar object  1050  may be a box, bag, bottle, irregularly shaped product, or any other three dimensional object having at least one non-planar surface. It will be appreciated that the RFID tag  1000  may be formed on the surface of a product itself, or on its primary or secondary packaging as desired, any of which may serve as the non-planar object  1050 . 
       FIG. 14  illustrates a method  1400  of manufacturing the RFID tag  1000  on the surface  1052  of the non-planar object  1050 . The method begins at  1402  where the non-planar object  1050  for receiving the RFID tag  1000  is selected. The construction of the RFID tag  1000  begins by forming the antenna  1002  on the surface  1052  of the non-planar object  1050  at step  1410 . At step  1412 , the reactive RFID strap  1004  is then positioned on the surface  1052  of the non-planar object  1050 . The reactive RFID strap  1004  is then coupled to the antenna  1002  to induce a far field antenna response as a functioning RFID tag  1000  at step  1414 . 
     Alternatively, and as also illustrated in  FIG. 14 , the method  1400  may begin at step  1402  wherein the non-planar object  1050  for receiving the RFID tag  1000  is selected. At step  1404 , the construction of the RFID tag  1000  may begin by forming and positioning the reactive RFID strap  1004  on the surface  1052  of the non-planar object  1050 , prior to forming the antenna  1002 . Then, at step  1406 , the antenna  1002  is formed on the surface  1052  of the non-planar object  1050 , and the reactive RFID strap  1004  is coupled to the antenna  1002  to induce a far field antenna response as a functioning RFID tag  1000  at step  1408 . More specifically, the coupling of the antenna  1002  to the reactive RFID strap  1004  can be via electric fields (E), magnetic fields (H), or by both electric (E) and magnetic (H) fields. Additionally, the reactive RFID strap  1004  may be physically coupled to the antenna  1002  if so desired. 
     The antenna  1002  may be deposited onto the non-planar object  1050  by spraying or printing a conductive ink to form the antenna  1002 . The ability to choose between spraying or printing to deposit a conductor onto a non-planar object, where an antenna shape may be adapted to function optimally, provides the manufacturer or other user with greater design flexibility and choice relative to the location on the non-planar object  1050  where an RFID tag may be formed. For example, on a bottle, it is common to try to form an RFID tag antenna on a flat surface on either the base or a top of the bottle. However, by using the methods  1400  depicted in  FIG. 14 , a user may form the antenna  1002  on any portion of the bottle surface, and adapt the same to the shape or contour of the bottle, so that in conjunction with the reactive RFID strap  1004  that is flexible enough to conform to the surface  1052 , a high performance RFID tag  1000  may be created. It must also be appreciated that, if the reactive RFID strap  1004  is not adequately flexible to attach to a highly complex three dimensional surface area where the antenna  1002  is formed, the reactive RFID strap  1004  may be placed on a relatively flat area and the antenna  1002  sprayed to create a physical connection between the antenna  1002  and the reactive RFID strap  1004 , thereby forming the final RFID tag  1000 . 
       FIGS. 15 and 16  illustrate a method  1500  of manufacturing a RFID tag  1000  adapted for a surface  1052  of a non-planar object  1050  based on the object shape and/or composition. More specifically, the method  1500  utilizes a camera system and a laser grid or the like to precisely scan the non-planar object  1050  onto which the antenna will be formed to insure that the antenna is correctly created, as there may be variations in the non-planar object  1050  and/or its placement on a production line. As with the prior methods  1400  depicted in  FIG. 14 , the reactive RFID strap  1004  may be placed on the surface  1052  of the non-planar object  1050  before or after creation of the antenna  1002  to form the high performance RFID tag  1000 . 
     More specifically, the method  1500  begins at step  1502  by determining the three dimensional position and shape of the non-planar object  1050  as the camera system scans the surface  1052 . At step  1504 , a design for an antenna  1002  suitable for a chosen location along the surface  1052  of the non-planar object  1050  is selected, compensating for surface shape and position. A design of a reactive RFID strap  1004  and a position for attaching the reactive RFID strap  1004  to the surface  1052  of the non-planar object  1050  is chosen at step  1506 . At steps  1508  and  1510 , the antenna  1002  is then sprayed or created onto the surface  1052  of the non-planar object  1050 , and coupled to the reactive RFID strap  1004  to form the RFID tag  1000  on the surface  1052  of the non-planar object  1050  to produce a far field antenna response. At step  1512 , a measurement of RF performance is conducted, either inline or offline. If the RF performance is acceptable at step  1512 , the method ends at step  1514  with the design having been successfully produced. If, on the other hand, the performance is not acceptable, the method of manufacture returns to step  1504  and the antenna design is adapted to optimize performance. 
     Alternatively, the reactive RFID strap  1004  may be positioned on the surface  1052  of the non-planar object  1050  before creation of the antenna  1002 . Additionally, the antenna  1002  may also be printed or otherwise positioned on the surface  1052  of the non-planar object  1050 . The coupling of the antenna  1002  to the reactive RFID strap  1004  can be via electric fields (E), magnetic fields (H), or by both electric (E) and magnetic (H) fields. Additionally, the reactive RFID strap  1004  may be physically coupled to the antenna  1002  if desired. 
       FIGS. 17-20B  illustrate a method  1700  of manufacturing a RFID tag  1000  adapted for a non-planar object  1050 . The method  1700  is adapted for creating a RFID tag  1000  comprising more than one layer, which is advantageous as metal and liquid objects can cause a significant drop in the performance of a standard RFID tag. As such, an RFID tag design utilizing an antenna formed on a separating material, such as a foam plastic or similar material with a high dielectric constant, for example, a flexible plastic with a ceramic dielectric powder such as, titanium dioxide or a barium titanate may be used.  FIG. 17  illustrates method  1700 , wherein the RFID tag  1000  is formed on the non-planar object  1050  by first depositing a separator  1020 , then an antenna  1002 , and a reactive RFID strap  1004  to form a “surface insensitive” RFID tag  1000 . 
     More specifically, method of manufacturing a RFID tag  1000  adapted for a non-planar object  1050  begins at step  1702 , wherein the non-planar object  1050  for receiving the RFID tag  1000  is selected. At step  1706 , the construction of the RFID tag  1000  begins with the separator  1020  being deposited onto the non-planar object  1050 , for example, by spraying. Next, at step  1712 , an antenna  1002  is formed on the separator  1020 . As previously stated, the antenna  1002  may be sprayed, printed, or otherwise positioned atop the separator  1020 . At step  1714 , a reactive RFID strap  1004  is attached to the separator  1020 , and coupled to the antenna  1002  to create the RFID tag  1000  with a far field antenna response at step  1716 . Alternatively, the reactive RFID strap  1004  may be positioned on the separator  1020  before creation of the RFID antenna  1002 . The coupling of the antenna  1002  to the reactive RFID strap  1004  can be via electric fields (E), magnetic fields (H), or by both electric (E) and magnetic (H) fields. Additionally, the reactive RFID strap  1004  may be physically coupled to the RFID antenna  1002  if desired. 
       FIG. 18  illustrates an alternative version of the method  1700 , wherein the antenna shape and reactive RFID strap location are adapted to a thickness measurement  1022  of the separator  1020 . More specifically, after the separator  1020  is deposited onto the surface of the non-planar object  1050  at step  1706 , the thickness  1022  of the separator  1020  is measured at step  1708 . At step  1712 , the antenna  1002  may be sprayed, printed, or otherwise positioned atop the separator  1020 . At step  1714 , a reactive RFID strap  1004  is attached to the separator  1020 , and coupled to the antenna  1002  to create the RFID tag  1000  with a far field antenna response at step  1716  as before. It will be appreciated that the separator  1020  does not need to be applied to a larger area of the non-planar object  1050  than the area required for the RFID tag  1000 . For example, the separator  1020  may be created only directly underneath the RFID tag  1000 , thereby blocking less of a surface  1052  of the non-planar object  1050  so as to not obscure other desirable qualities such as branding or marking. 
       FIG. 19  illustrates a further alternative version of the method  1700 , wherein the accuracy of the initially applied material for the separator  1020  is insufficient to permit formation of a stable RFID tag  1000 . In this particular embodiment, the thickness  1022  of the separator material  1020  is adapted to insure stability of the RFID tag  1000 , and may be rolled to a required or desired thickness. Further, if the separator material  1020  is capable of curing with heat, the roller may be suitably heated for use to both roll and cure the separator material. More specifically, after the separator material  1020  is deposited onto the surface of the non-planar object  1050  at step  1706 , the desired thickness  1022  of the separator material  1020  may be achieved at step  1708  by, for example, hot roll. The separator material  1020  may also be cured if required or otherwise desired at this stage. At step  1712 , the antenna  1002  may then be sprayed, printed, or otherwise positioned atop the separator material  1020 . Then, at step  1714  (as shown in  FIG. 17 ), a reactive RFID strap  1004  is attached to the separator material  1020  and coupled to the antenna  1002  to create the RFID tag  1000  with a far field antenna response as previously described. 
       FIG. 20A  illustrates an alternative version of the method  1700 , wherein at least a portion of the antenna structure is deflected with respect to another portion of the antenna structure. The ability to create a deflected antenna structure is particularly desirable, as successfully creating conductors around sharp corners by printing is difficult. More specifically, the separator material  1020  may further comprise a ramped portion  1024 , and be sprayed or otherwise applied so that the ramped portion  1024  is sloped or tapered downwardly to meet a surface  1052  of the non-planar object  1050 . Once the separator material  1020  with the ramped portion  1024  is deposited at step  1706 , the antenna  1002  is printed or sprayed onto the separator material  1020 , including down along the ramped portion  1024  and into proximity contact with the surface  1052  of the non-planar object  1050 , as best shown in  FIG. 20A  at step  1712 . The reactive RFID strap  1004  may then be attached to the separator material  1020  and coupled to the antenna  1002  to create the RFID tag  1000  with a far field antenna response at  1716  as described above. This method is particularly effective for forming “on-metal” type RFID tags, wherein the non-planar object  1050  has a metallic surface  1052 . 
       FIG. 20B  illustrates yet a further alternative version of the method  1700 , wherein at least a portion of the antenna structure is deflected with respect to the other part of the antenna structure and the RFID tag comprises both a top and a bottom conductor. More specifically, the method  1700  further comprises first applying a base conductor  1026  to the surface  1052  of the non-planar object  1050  at step  1704 . Then, at step  1706 , the separator material  1020  is sprayed or otherwise deposited atop the base conductor  1026  so that the ramped portion  1024  is sloped downwardly to the base conductor  1026 . Once the separator material  1020  with the ramped portion  1024  is deposited at step  1706 , the antenna  1002  and reactive RFID strap  1004  are printed or sprayed onto the separator material  1020  down along the ramped portion  1024  and into proximity contact with the base conductor  1026  to create the RFID tag  1000  with a far field antenna response at step  1712 . This allows for a RFID tag structure wherein the base conductor  1026  isolates the top conductor (i.e., antenna  1002 ) acting as the radiating antenna from the non-planar object  1050 , and is particularly effective in applications in which the non-planar object  1050  contains a high loss liquid such as water. 
     What has been described above includes examples of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
