介绍了基于亚波长介质光纤技术的Y分支和多模功分器的设计和特性。两者都已成功地建立在介质波导的光学领域，并适用于W波段频率（75-110 GHz）。两种功率分配器均由交联聚苯乙烯Rexolite 1422制成，并经过铣削加工。模拟预测插入损耗在3.5和4 dB之间，而电气特性显示插入损耗在3.5和5 dB之间。与Y分支分频器相比，多模式功分器具有最佳性能，插入损耗低1-1.5 dB。
The design and characterisation of two different power divider techniques, i.e. Y‐branch and multimodal power dividers, based on subwavelength dielectric fibre technology is presented. Both have been successfully established in the optical domain for dielectric waveguides and are adapted to W‐band frequencies (75–110 GHz). Both power dividers are made out of the cross‐linked polystyrene Rexolite 1422 and have been processed by milling. Simulations predicted insertion losses between 3.5 and 4 dB while the electrical characterisation showed insertion losses between 3.5 and 5 dB. The multimodal power divider has the best performance with 1–1.5 dB lower insertion losses compared with the Y‐branch divider.
