NI AWR Design Environment
EL SEGUNDO, Calif.
A new application note featuring NI AWR Design Environment discusses a novel method used for optimizing radio-frequency identification (RFID) antennas and describes two examples of RFID antennas created using this methodology. Because ultra-high-frequency RFID tag antennas need to be inexpensive, efficient, robust for the installation environment, and immune to change in electrical behavior due to proximity to the mounting platform, there are several challenges for RFID antenna designers. The design approach outlined in this application note utilizes AntSyn™, novel NI AWR software antenna synthesis and optimization technology, which employs evolutionary algorithms (EAs) to efficiently explore the design space and automatically determine the best performance options.
