A New Conductive Ink for Microstrip Antenna and Bioinspired FSS Designs on Glass and Fiberglass Substrates

Abstract This paper describes an investigation of the possibility of using a new conductive ink, insted of copper clad laminates, in the manufacturing of microstrip patch antennas on glass and fiberglass substrates and of bioinspired frequency selective surfaces (FSSs) on fiberglass substrates for wireless communication systems. The new conductive ink is developed using synthesized nitrocellulose which, in ethyl acetate solution, works as a bonding agent and carrier for the formation of a conductive film. The load used in the fabrication process is silver metallic powder. Simulation and analysis are performed using Ansoft Designer and HFSS softwares. Microstrip antenna and FSS prototypes are fabricated and measured for comparison purpose. An agreement is observed between simulation and measurements results.

摘要 本文研究了采用新型导电墨水（conductive ink）替代覆铜箔层压板（copper clad laminates），在玻璃及玻璃纤维基板上制备微带贴片天线（microstrip patch antennas），以及在玻璃纤维基板上制备面向无线通信系统的仿生频率选择表面（frequency selective surfaces，FSS）的可行性。该新型导电墨水以合成硝化棉为原料开发而成：在乙酸乙酯（ethyl acetate）溶液中，硝化棉可作为粘结剂（bonding agent）与载体，用于形成导电薄膜（conductive film）；制备过程中所使用的填料为银金属粉末（silver metallic powder）。本研究采用Ansoft Designer与HFSS软件开展仿真与分析工作，并制作了微带天线及FSS原型进行实测对比。结果表明，仿真结果与实测数据具备良好的一致性。
