UHF ceramic tag is a kind of electronic tag that based on ceramic material, which has excellent electrical performance and high temperature resistance. It is widely used in high temperature, humidity, gasoline or an environment with greater temperature difference. It can also be used for traceablity and anti-counterfeiting in IT asset management, network and communication facilities management, tools and parts management, mold、 engine and other precision instruments. Tansoc starts to research and develop UHF ceramic tag is based on one of our middle eastern customer who works for special car refueling and tank management system. The customer requires the tag must satisfy with strict requirement in high temperature, oil spots, anti-metal and anti-dismantle. After two years research, we have adopted special UHF anti-tamper chip, with special antenna design and high precision tangents on ceramic substrate to meet customer’s requirement.
