摘要
本文介绍了 D 波段沟槽间隙波导(GGW)滤波器的设计和增材制造(AM)。对于这种滤波器,需要制造非常小的周期性针脚结构。传统的数控铣制造这些结构非常耗时,而高精度铣床又非常昂贵。因此,必须采用丝网印刷等其他制造工艺,才能经济高效地大量生产。本文介绍了丝网印刷工艺,并通过一个 D 波段三阶带通滤波器原型验证了丝网印刷工艺在毫米波领域生产 GGW 元件的适用性。
3-D Screen Printing: Efficient Additive Manufacturing of Groove Gap Waveguide Filters in D-Band
In this letter, the design and additive manufacturing (AM) of a groove gap waveguide (GGW) filter in the D-band is presented. For this kind of filter, the manufacturing of very small periodic pin structures is necessary. The conventional manufacturing of these structures by CNC milling is time-consuming, and high-precision milling machines are extremely expensive. Other manufacturing processes such as screen printing are, therefore, required for the cost-effective and efficient production of large quantities. The screen printing process is presented, and its suitability for the production of GGW components in the millimeter-wave area is validated by a third-order bandpass filter prototype in D-band, which was manufactured and electrically characterized.
