1. A system comprising:
- an airline baggage handling and transport facility to receive a set of airline baggage, with each airline baggage having a label physically associated with the respective baggage, the label comprising a Radio Frequency Identification (RFID) tag comprising a thin base layer having a mounting portion on one surface, one or more antennas disposed on the base layer, and a radio frequency transceiver integrated circuit disposed adjacent the mounting portion having a memory for storing a unique ID, wherein the RFID tag is of non-uniform thickness, including a first thickness at a first location on the RFID tag that includes the base layer and a second thickness, greater than the first thickness, at a second location that includes the mounting portion; and
an interrogation system configured to use RF signals to read the unique ID from the RFID tag, wherein the unique ID corresponds to data related to airline baggage transport.

Abstract
The present invention teaches a method of manufacturing an enclosed transceiver, such as a radio frequency identification (“RFID”) tag. Structurally, in one embodiment, the tag comprises an integrated circuit (IC) chip, and an RF antenna mounted on a thin film substrate powered by a thin film battery. A variety of antenna geometries are compatible with the above tag construction. These include monopole antennas, dipole antennas, dual dipole antennas, a combination of dipole and loop antennas. Further, in another embodiment, the antennas are positioned either within the plane of the thin film battery or superjacent to the thin film battery.
