Due to rapid growth of Internet-of-Things (IoT), RFID has been increasingly used in business environment and people’s daily lives. However, the limitation of reliability impedes the development and application of RFID. Today, almost all reader antennas can only offer 2-axis polarisation, which has posed the challenge of unpredictability in reading tagged objects even within specified reading range. Thus, there are always dead zones that linearly polarised tag antennas cannot be read.
To address this issue, the LSCM R&D Centre has worked together with the University of Hong Kong and proposed a novel system that can boost and improve reliability of RFID reading rate significantly. The 3-axis polarisation technology is a ground-breaking concept that overcomes the shortcomings of conventional reader antennas, which are generally supplied with configuration of 2-axis polarisation.
It can be ensured that each orientation along the polarised tag antennas can be read by applying a 3-axis polarisation approach, while maintaining a low profile feature. This technology will greatly improve the reliability and flexibility of existing RFID systems. The applied research project will be completed in April 2016 with availability of low profile 3-axis poliarisation near field UHF RFID antenna prototypes. |
