Summary:
The fabrication of conductive lines or connectors is vital in electronic industry. Various methods have been widely developed and employed. Typically, electroplating, photolithography and etching processes are adopted for manufacturing. However, this subtractive technique involves many complicated steps, those results in time consuming, generating waste chemicals and materials. The purposed additive approach with the adaptation of conventional ink-jet printer promises simplicity and reduction in manufacturing cost. Furthermore, the technique is suitable for foldable organic substrates, such as paper. This sets a foundation of 'green' electronics with the use of environmentally friendly process and materials [1]. An excellent demonstration of this affordable fabrication technology is through RFID antennas. The emerging UHF RFID technology is potentially applied to a variety of applications. Especially when the fabrication cost is comparable to that of bar codes, the paper-based RFID can be used in almost any low cost applications. In this article, ink-jet printed RFID antennas in different configurations are demonstrated, along with their measured performances compared to simulation results.
