RFID吸波材料
在RFID（125KHZ,13.56MHz）设备中，回型天线标签要集成或贴合到电子设备里，作为读卡部件发挥功能，往往因空间有限，不可避免要将RFID（125KHZ,13.56MHz）标签贴在PCB板或电池等金属物体表面。这样一来，回型天线标签在读卡器发出的信号作用下激发感应出的交变电磁场很容易受到金属的涡流衰减作用而使信号强度大大减弱，导致读取过程失败。因此，为了产品能够更好的应用读卡，需要在产品中增加RFID吸波材料用于改善RFID读写器、标签在金属上的接收灵敏度。
In RFID ( 125KHZ, 13.56MHz ) equipment, back to the antenna to be integrated or label attached to an electronic device,
as the card member function, often because of the limited space, inevitably will be RFID ( 125KHZ, 13.56MHz ) label on
the PCB board or cell surface of metal objects. In this way, back to the antenna label in the reader a signal under the
excitation induction of alternating electromagnetic field is susceptible to metal vortex attenuation and make the signal
strength is weakened greatly, causes the read process failure. Therefore, in order to products can better application
card, need in products increased RFID wave absorbing materials for improving RFID reader, tag in the metal receiving
sensitivity.
