    • A method for producing an antenna structure for an RFID device, a dry toner for use in producing an antenna for an RFID device and a RFID device comprising an antenna structure made of fused toner are disclosed. In a method for producing an antenna structure for an RFID device, a dry toner comprising a polymeric binder and metallic particles is provided. The toner comprises particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction. In the method, a continuous layer of the dry toner is applied to a substrate in a desired shape of an antenna via an electrophotographic printing process, and subsequently the toner is fused to the substrate by heating the toner above its glass transformation temperature. The dry toner for use in producing an antenna for an RFID device comprises toner particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging. The toner particles comprise a polymeric binder and metallic particles, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction.
    • 公开了一种用于制造用于RFID设备的天线结构的方法,用于制造用于RFID设备的天线的干式调色剂和包括由熔融调色剂制成的天线结构的RFID设备。 在制造RFID装置的天线结构体的方法中,提供了包含聚合物粘合剂和金属颗粒的干燥调色剂。 调色剂包括具有允许进行摩擦带电的电阻或允许感应充电的电阻的颗粒,其中所述金属颗粒是在至少一个方向上具有低于约500nm的平均粒度的纳米颗粒。 在该方法中,通过电子照相印刷方法将干式调色剂的连续层施加到所需形状的天线,然后通过将调色剂加热到其玻璃化转变温度以上将调色剂熔合到基底上。 用于生产用于RFID设备的天线的干燥调色剂包括具有允许摩擦充电的电阻的调色剂颗粒或允许感应充电的电阻。 调色剂颗粒包括聚合物粘合剂和金属颗粒,其中所述金属颗粒是在至少一个方向上具有低于约500nm的平均粒度的纳米颗粒。
