【摘要】：针对目前射频识别(RFID)标签天线制备成本高、工艺复杂等问题,提出微滴按需喷射3D打印与化学沉积技术相结合制备半波偶极子天线的方法。利用构建的气动式双喷头微滴喷射系统,采用试验研究的方法,对系统按需喷射条件下产生硝酸银与抗坏血酸微滴的一致性以及基板运行速度对成线均匀性的影响进行研究,并对成形导线的电阻率进行测试;在此基础上设计、仿真和制备了半波偶极子天线,对其性能参数进行了测试。结果表明:系统产生的微滴均匀性较好;基板速度小于或等于0.5mm/s时,硝酸银成线边缘光滑度较好;成形导线的电导率为1.57×10~(-5)Ω·m;打印成形的半波偶极子天线谐振频率、谐振点回波损耗S_(11)参数等与仿真结果具有较好的一致性。为RFID标签天线提供了一种低成本制备方法。
[Abstract]:In order to solve the problems of high cost and complex process, the RFID tag antenna is prepared. A method of fabricating half-wave dipole antenna by 3D printing on demand and chemical deposition is proposed. The pneumatic dual-head micro-droplet injection system is used to study the system. The uniformity of silver nitrate and ascorbic acid droplets and the effect of substrate speed on the uniformity of wire formation were studied under the condition of on-demand injection, and the resistivity of the formed wire was measured. On this basis, the half-wave dipole antenna is designed, simulated and fabricated, and its performance parameters are tested. When the substrate velocity is less than 0.5 mm / s or equal to 0.5 mm / s, the edge of silver nitrate line is smooth; The conductivity of the formed wire is 1.57 脳 10 ~ (-5) 惟路m; The printed half-wave dipole antenna resonant frequency, resonance point echo loss and so on are in good agreement with the simulation results, which provides a low-cost preparation method for RFID tag antenna.
