论文摘要
我们开发了一个宽带准精光谱滤器滤波器，覆盖了170-520 GHz，通过利用市售灵活的印刷电路（FPC）制造技术的最新进步。我们使用铜图案设计并制造了三层堆积的六角六角网格金属网眼，并在聚酰亚胺基板上的铜图案最狭窄的线宽为$ 50〜μ \ mathrm {m} $。测得的频率传递形状通过数值模拟成功地复制，使用一组与制造金属网格的尺寸一致的参数。基于FPC的金属网格过滤器将为毫米/亚毫米波的按需开发提供新的途径，以低成本且周转时间很短。
We developed a wideband quasi-optical band-pass filter covering 170-520 GHz by exploiting the recent advancements in commercially available flexible printed circuit (FPC) fabrication technologies. We designed and fabricated a three-layered stack of loaded hexagonal grid metal meshes using a copper pattern with a narrowest linewidth of $50~μ\mathrm{m}$ on a polyimide substrate. The measured frequency pass-band shape was successfully reproduced through a numerical simulation using a set of parameters consistent with the dimensions of the fabricated metal meshes. FPC-based metal mesh filters will provide a new pathway toward the on-demand development of millimeter/submillimeter-wave quasi-optical filters at low cost and with a short turnaround time.
