ABSTRACT:
An enclosed transceiver includes an integrated circuit and a battery together laminated between two films. Printed conductors on each film couple operative power to the integrated circuit. Other-printed conductors form an antenna coupled to the transceiver for sending and receiving signals. In a preferred embodiment, the integrated circuit has three terminals. The first terminal is connected to a first side of a thin film battery. The second terminal is connected to a first side of a printed loop antenna. The third terminal serves two purposes being connected to the second side of the battery and to the second side of the loop antenna. The enclosing films are treated with silicon nitride for hermeticity. Enclosed transceivers of the present invention are suitable for mass production in web, sheet, and tape formats. Such transceivers are useful as stamps, labels, and tags in object tracking systems including systems for mail delivery, airline baggage tracking, and inventory control.
