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 lead to reading data from RF tags on another antenna. This phenomenon is referred to as antenna coupling. We have created a video explaining the effects of antenna coupling, and we will be releasing it.

basic information
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 feed power to the antennas 2. Demonstration 02:03～ We will confirm the occurrence of antenna coupling through an actual operation demonstration. Antenna coupling can be addressed by increasing the spacing between the antennas.

Company information
Founded in 1894 as a textile company, Takaya Textile expanded and established its electronics division in 1966, starting the assembly of transistor radios. Today, in addition to contract manufacturing services (EMS) related to electronic devices, the company actively manufactures and sells various electronics, including in-circuit testers (printed circuit board inspection devices) and RFID (a technology that enables information exchange through short-range wireless communication from tags containing IC information), as well as IT consulting and system solutions, both domestically and internationally. We continue to evolve as a corporate group that contributes to societal development, with textiles and electronics as our dual pillars.
