设计了一种工作在10 ~ 18 GHz扩展Ku波段的多层介质棒波导。所提出的设计是完全开发和制造的增材制造技术，特别是熔融沉积成型（FDM）。多层DRW由印刷有定制的陶瓷复合材料和低介电常数ABS包层的介质芯形成。这两种材料都与FDM兼容。器件性能的测量与不存在的低介电常数包层。多层DRW的插入损耗小于0.012 dB/mm，并且在整个频率范围内由于每个波导馈电过渡福尔斯引起的衰减落在0.29至0.98 dB内。此外，包层的存在将1 dB截止频率扩展了2 GHz，从而将1 dB工作带宽提高了50%。
A multilayer dielectric rod waveguide (DRW) is designed for operation at an extended Ku-band from 10 to 18 GHz. The proposed design is fully developed and fabricated by using additive manufacturing technologies, particularly fused deposition modeling (FDM). The multilayer DRW is formed by a medium-Λ dielectric core printed with a custom-made ceramic composite and a low permittivity ABS cladding. Both materials are compatible with FDM. Device performance is measured with and without the presence of the low permittivity cladding. The insertion loss of the multi-layer DRW is less than 0.012 dB/mm and the attenuation due to each waveguide feed transition falls within 0.29 to 0.98 dB in the entire frequency range. Additionally, the presence of the cladding extends the 1 dB cut-off frequency by 2 GHz, thus improving the 1dB operational bandwidth by 50 %.
