Title: Po-Kuang Chang: RFID Antenna Testing Innovation
Introduction
Po-Kuang Chang is an inventor based in Taoyuan, Taiwan. His patent work addresses antenna testing for radio-frequency identification (RFID) tags, with a focus on compensating for antenna axial ratio.
Latest Patents
Chang is associated with 1 patent: “Apparatus and Method for Compensating the Axial Ratio of an Antenna for Testing RFID Tags.” The invention describes a method and apparatus that determine an RFID tag’s polarization angle by rotating the tag and antenna around perpendicular axes and comparing the tag’s initial and post-rotation positions. A lookup table then provides a compensation value to adjust the antenna’s axial ratio, supporting RFID tag testing in different orientations.
Career Highlights
Chang works at the Industrial Technology Research Institute. His patent reflects work on improving the reliability of antenna measurements used to test RFID tags and tagged products.
Collaborations
Chang’s listed coworkers include Min-Kao Hong and Shang-Sian You.
Conclusion
Po-Kuang Chang’s patent focuses on compensating antenna axial ratio during RFID testing, contributing a practical approach to evaluating tags across multiple orientations.
