[Video] Effects of Layering RF Tags on HF Band RFID Reader Writers

【Basic Knowledge of RFID】What is an RFID Reader/Writer? The Impact of Layering RFID Tags

We have created a video explaining the effects of stacking RF tags, and we will publish it. When RF tags are stacked, their communication performance decreases, making stable communication impossible. This is because the antennas of the RF tags overlap, and due to mutual inductance, the resonant frequency of the RF tags shifts towards the lower frequency. The degree of impact on communication performance varies depending on the spacing between the RF tags when stacked and the number of tags stacked. 1. About the principle Explanation of the principle behind the decrease in communication performance when stacking RF tags. 2. Demonstration Operational demonstration explaining the following content: - Stacking RF tags decreases communication performance. - The narrower the spacing between RF tags when stacked, the more communication performance decreases. - The more tags stacked, the greater the decrease in communication performance.
