Abstract
Apparatus and methods for providing a substantially surface independent tagging system are disclosed. A resonant dielectric cavity is defined between upper and lower conducting layers, and closed at one end by a conducting base portion. Incident radiation couples into the cavity and is resonantly enhanced. An electronic device or tag paced at the edge of the cavity experiences a high electric field strength on account of this enhancement and is driven into operation.
Claims11
A substantially surface independent EM tag comprising:
- an electromagnetic radiation decoupler comprising a cavity structure which comprises a conducting base portion connected to a first conducting side wall formed by a first conducting layer and a second conducting side wall formed by a second conducting layer, the first conducting side wall and the second conducting side wall being substantially parallel to each other, said first and second conducting layers respectively defining upper and lower layers;
- a cavity structure area of absence;
- and
- an electronic device mounted in the cavity structure area of absence, the electronic device comprising a chip coupled to an integral antenna.
