Synthesizing UHF RFID Antennas On Dielectric Substrates

Radio-frequency identification (RFID) technology uses electromagnetic fields to automatically identify and track objects with tags containing electronically stored information. This application note discusses a new approach to optimizing RFID antennas for this technology with the use of the new NI AWR Software product AntSyn™ antenna synthesis and optimization technology. This method employs evolutionary algorithms (EAs) to explore the design space and automatically determine the best performance options. Download the full application note for two examples of RFID antennas created using this technique.
