Basic Knowledge of HF Band RFID: What Are the Effects of Antenna Induction? Explained Clearly in a YouTube Video.
When multiple antennas are installed in close proximity, they can couple through electromagnetic induction, which may result in reading data from RF tags on another antenna. This phenomenon is referred to as antenna induction. We have created a video explaining the effects of antenna induction, and we will be releasing it.

1. What is antenna coupling 00:09～ I will explain the situations in which antenna coupling occurs. - When non-fed antennas are in close proximity - When multiple reader/writers are installed to simultaneously power the antenna 2. Demonstration 02:03～ We will confirm the occurrence of antenna coupling through an actual operation demonstration. Antenna coupling can be mitigated by increasing the distance between the antennas.
