Abstract
An RFID transponder (1) comprising a radiating antenna (2) and a pod (3) and a method for manufacturing a panel (29) comprising pods (3) are disclosed.
Claims13
An RFID transponder, comprising:
- a radiating antenna and a pod, the radiating antenna having a coupling area for the pod, wherein:
- the pod is situated at the coupling area, and the pod comprises a first end and a second end and a casing between the first end and the second end, at least part of the casing comprising dielectric layers one above the other,
- upper arms on a surface of one of the dielectric layers, lower arms on a surface of another layer of the dielectric layers, and via holes connecting the upper and lower arms form a planar helix antenna that is configured to extend between the first end and the second end,
- the planar helix antenna has a first antenna end and a second antenna end,
- the first antenna end is connected to a second electrically conductive connection and the second antenna end is connected to a first electrically conductive connection,
- an integrated circuit on a chip is coupled to the first electrically conductive connection and the second electrically conductive connection inside the pod,
- a lead-through is configured to run between the upper arms and the lower arms on a surface of one of the dielectric layers,
- at least the first electrically conductive connection is electrically connected to the second antenna end or the second electrically conductive connection is electrically connected through the lead-through to the first antenna end, and
- the radiating antenna and the planar helix antenna are configured to couple without a physical contact.
