Abstract
A wireless tag comprises a chip; an antenna; at least one conductive structure, the conductive structure and the chip being coupled by a common electrical connection to ground; and a filter electrically interposed along an electrical connection between the chip and the conductive structure; wherein the filter causes a reduction in amplitude of a signal passing between the conductive structure and the chip or an electrical disconnection between the conductive structure and the chip at around a prescribed frequency.
Claims23
A wireless tag, comprising:
- a chip;
- an antenna;
- at least one conductive structure, the conductive structure and the chip being coupled by a common electrical connection to ground;
- and
- a filter electrically interposed along an electrical connection between the chip and the conductive structure;
- wherein the filter causes an electrical disconnection between the conductive structure and the chip at around a prescribed frequency, wherein the filter comprises an inductor and a capacitor in parallel, the inductor being formed by an arcuate single layer conductor that surrounds interdigitated fingers formed of a single layer conductor that extend in an interleaved manner inward from the arcuate conductor.

A substrate for a wireless tag, comprising:
- electrical contacts for coupling to a chip;
- an antenna;
- at least one conductive structure, the conductive structure and at least one of the electrical contacts for coupling to the chip being coupled by a common electrical connection to ground;
- and
- a filter electrically interposed along an electrical connection between the at least one of the electrical contacts for coupling to the chip and the conductive structure;
- wherein the filter causes an electrical disconnection between the conductive structure and the chip at around a prescribed frequency, wherein the filter comprises an inductor and a capacitor in parallel, the inductor being formed by an arcuate single layer conductor that surrounds interdigitated fingers formed of a single layer conductor that extend in an interleaved manner inward from the arcuate conductor.

A wireless tag, comprising:
- a chip;
- an antenna;
- at least one conductive structure, the conductive structure and the chip being coupled by a common electrical connection to ground;
- and
- a choke electrically interposed along an electrical connection between the chip and the conductive structure;
- wherein the choke acts as a filter to cause a reduction in amplitude of a signal passing between the conductive structure and the chip at around a prescribed frequency, wherein the filter comprises an inductor and a capacitor in parallel, the inductor being formed by an arcuate single layer conductor that surrounds interdigitated fingers formed of a single layer conductor that extend in an interleaved manner inward from the arcuate conductor.
