First Claim
1. A wireless communication device, comprising:
- a radio frequency identification (RFID) tag, comprising;
an RFID circuit packaged within a chip carrier package, wherein the chip carrier package bonds out at least a first antenna connection for the RFID circuit;
an antenna including at least a first conductive lead interfaced with the at least the first antenna connection;
a first spacer having a first dielectric constant, wherein the chip carrier package and the at least the first conductive lead are coupled to a first side of the first spacer; and
a second spacer having a second dielectric constant greater than the first dielectric constant and coupled to a second side of the first spacer, wherein the second spacer is adapted to isolate the RFID circuit from a metal surface.

Abstract
Methods and systems for wireless devices are disclosed. According to one system, a radio frequency identification (RFID) tag includes an RFID circuit packaged within a chip carrier package. The chip carrier package bonds out a first antenna connection for the RFID circuit. An antenna including a conductive lead is interfaced with the first antenna connection. The chip carrier package and the first conductive lead are coupled to a first side of a first spacer. A second spacer having a second dielectric constant greater than the first dielectric constant is coupled to a second side of the first spacer. The second spacer isolates the RFID circuit from a metal surface.
