Abstract
An RFID device includes an antenna defining a gap, with an RFID chip electrically coupled to the antenna across the gap. The RFID chip may be incorporated into an RFID strap, in which a pair of connection pads is connected to the RFID chip, with the connection pads connected to the antenna on opposite sides of the gap. Alternatively, the antenna may be connected to bond pads of the RFID chip. At least a portion of the antenna has a cross section with an at least partially curved perimeter. The cross section of the antenna may be differently shaped at different locations, such as having a flattened oval shape at one location and a substantially circular shape at another location. A portion of the cross section of the antenna may have a non-curved, relatively sharp edge, which may break through an outer oxide layer of a connection pad.
