Abstract

The present invention provides systems and methods for transmitting and receiving information from a radio frequency (RF) transponder. A conductive adhesive connects an antenna in a non-metallized region to a metallized region. This feature transforms the entire metallized region of the radio frequency device (i.e., the remainder of the metallized material outside the non-metallized region) into an antenna.

Claims

at least one metallized region;

at least one non-metallized region;

at least one antenna on the at least one non-metallized region;

at least one radio frequency chip in electrical communication with the at least one antenna; and

at least one electrical connection connecting the at least one antenna to the at least one metallized region, wherein the at least one antenna is electrically interspersed between the radio frequency chip and the at least one metallized region, such that the at least one metallized region acts as a second antenna or as a part of the at least one antenna; and

,

wherein the at least one metallized region is not in direct electrical communication with the at least one radio frequency chip.
