Printed antennas, methods of printing an antenna, and devices including the printed antenna

摘要

Wireless devices such as sensors, interactive displays and electronic article surveillance (EAS) and/or radio frequency identification (RFID) tags including integrated circuitry and an antenna and/or inductor printed thereon, and methods for making and using the same, are disclosed. The device generally includes an integrated circuit on a substrate and an antenna, directly on the substrate and/or the integrated circuit, in electrical communication with the integrated circuit. The method of making a wireless device generally includes forming an integrated circuit on the substrate and printing at least part of an antenna or antenna precursor layer on the integrated circuit and/or substrate. The present invention advantageously provides a low cost wireless device capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional devices.

主权项

1. A method of manufacturing a device, comprising:
a) forming an integrated circuit comprising at least one patterned conductor thin film, at least one patterned semiconductor thin film and at least one patterned insulating thin film on a first substrate; and b) printing an antenna or antenna precursor layer on the integrated circuit or on both the first substrate and the integrated circuit, at least part of the antenna being printed on the integrated circuit, and the antenna being in electrical communication with the integrated circuit.
