nfc ferritesheet(铁氧体片)：
rfid铁氧体应用在rfid低频（lf）或高频（hf）的原理：
当电子标签直接贴在金属表面上时，因为金属涡电流的影响，使天线无法利用磁生电的原理驱动晶片并回传讯号，造成无法读取的结果。在贴上rfid铁氧体材料后，磁束经吸波材料的路径形成完整磁场，使标签可以顺利被读取设备读取到。应用在lf（低频）hf（高频）rfid时由于铁氧体的磁导率比一般的抗金属材料高，当抗金属材料厚度一样时，磁导率越高的材料可以通过越多的磁束，使金属的影响越小，进而使得读卡距离越远，所以我们推荐磁导率高的铁氧体材料运用在rfid读卡器及标签上，提高读卡灵敏度，增强读卡距离。
the nfc ferritesheet (ferritechip):
rfid ferrite applicationprinciple of rfid low frequency (lf) orhigh-frequency (hf):
when electronic tag directlyattached to the metal surface, since the impact ofthe metal eddy currents, so that the antenna can not takeadvantage of the principles of themagnetic health electricity drives wafer and backscattersignals, causing the results can notbe read. rfid-ferrite materials,the magnetic flux through the path ofthe absorbing material to form a completemagnetic field, smooth reading device reads thelabel. application in a lf(low frequency), hf(high frequency) rfid, becausethe magnetic permeability of the ferrite ishigher than the general anti-metalmaterial, when the thickness of theanti-metal material is the same, the higher thepermeability of the material can be more magneticfluxes , the influence of the metalis smaller, thus making the reading distancefarther, so we recommend high permeabilityferrite material used in rfid reader andtag, improve reader sensitivity, enhancedreading distance.
