供应125k/13.56mhz天线/线圈抗金属材料：
抗金属吸波材料（铁氧体）主要在低频lf（125khz）及高频hf（13.56mhz）的金属环境中使用，当rfid标签或rfid读写器贴在金属表面时，由于受到金属干扰影响，造成实际读取距离会比预期距离要短很多，甚至会造成读卡失败，为防止金属干扰对读卡的影响，传统的设计方法是在rfid天线与金属之间加一个非金属衬垫使之距离增大，但是这种设计方法会使rfid标签或读写器变厚；新的设计方法是将抗金属吸波材料（铁氧体）贴在rfid天线后再贴在金属表面上，这样即增大读卡距离提高读卡灵敏度，又让rfid标签或读写器变得轻薄。
anti the metal absorbing material (ferrite)main use in metal environment of lowfrequency lf (125khz) and high-frequency hf (13.56mhz) rfidtags or rfid reader attached to the metalsurface, due to metal interference,cause actual reading distance than the expecteddistance shorter lot, even cause the readerto fail, is prevent metalinterference impact on the reader,the traditional design methods between rfid antennawith metal plus a non-metallic linersodistance increases, but this design approachwill make rfid tag or readerthickening; design anti the metalabsorbing materials (ferrite) attached to the rfid antennaand then paste in the metalsurface, suchthat is, to increasethe reading distance increase reader sensitivity,letting the rfid tag or reader becomesthin.
