Patent ID: 7573425

Claim:
An antenna configured for a radio frequency identification (RFID) device, the antenna comprising: a first conductive element over a substrate, the first conductive element extending between a first end and a second end; a second conductive element over the substrate, the second conductive element including a first path extending between a third end and a fourth end, a second path extending from the third end to a fifth end, and a third path extending from the third end to a sixth end, wherein the first conductive element comprises at least one bend extending from the second end to the first end toward the fifth end so that the first end of the first conductive element is separated from but near one of the fifth end of the second path or the sixth end of the third path of the second conductive element, wherein the first end of the first conductive element is separated from the fifth end of the second path of the second conductive element by a gap, and wherein a bandwidth of the antenna is a function of a length of the gap; wherein the second end of the first conductive element is electrically connected to a first pin of a chip, and the fourth end of the first path of the second conductive element is electrically connected to a second pin of the chip.
