[Video] The Effects of Metal Proximity in HF Band RFID and Their Countermeasures
"Basic Knowledge of HF Band RFID" explains the effects of proximity to metal and countermeasures in an easy-to-understand manner in a YouTube video.
When a reader/writer (antenna) comes close to metal, communication performance (distance, area) may decrease. This is especially true when there is metal behind the antenna, as it is most affected by the metal. Therefore, we have created a video that explains the impact of metal proximity on the antenna and the countermeasures, and we are now releasing it.
basic information
1. About the Principle I will explain the mechanism by which the communication performance decreases when the antenna approaches metal. 2. Demonstration Through an actual operation demonstration, we will confirm that the communication performance (communication distance) changes depending on the presence or absence of metal behind the antenna. 3. Countermeasures I will explain the countermeasures to prevent the effects of metal. - Increase the distance between the antenna and metal - Place ferrite between the antenna and metal - Optimize the characteristics of the antenna according to the installation environment

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