摘要： 随着直接在印刷电路板（PCB）或金属化的介质板上制作基片集成非辐射介质（SINRD）波导的概念提出，如何用平面电路的方式激励此种SINRD波导是今后广泛应用SINRD波导电路的要解决的关键技术之一，这是因为这一技术的解决可以为平面多层化毫米波系统在更高频率上的使用打下基础.本文提出了一种利用微带线到槽线过渡结构，然后利用槽线准TEM波主模和SINRD波导LSM₁₁主模的场型相似性，用槽线去激励PCB型SINRD波导的新型馈电结构.通过使用多层结构，电路由两层的ArlonTC600的PCB组成，从微带结构到槽线的过渡电路可以直接焊接在稍薄的板子上.接下来可在接近SINRD波导介质条带的中心位置激励所需的工作模式LSM₁₁模，这种槽线到SINRD波导的配置可以获得更宽的带宽和高度的集成.仿真和实验结果证实了上述观点的正确性.

Abstract: Since the substrate integrated nonradiative dielectric(SINRD)waveguide fabricated directly on printed circuit boards(PCBs)was proposed,it has been a key issue how to excite the SINRD waveguide by using a planar structure.This paper presents a novel planar transition of the SINRD waveguide.The transition first uses a transition structure from microstrip to slotline.After that,since the field distribution of quasi-TEM mode of a slotline is similar to that of SINRD waveguide LSM₁₁ mode,the main mode LSM₁₁ of SINRD waveguide can be excited very well.By using multi-structure,two Arlon TC600 boards with different heights,the transition from microstrip to slotline can be directly fabricated on the thinner board.In this way,the good performance of the transition from microstrip to slotline can be achieved while the slotline is located almost in the middle of the dielectric strip of SINRD waveguide therefore can be used to excite the SINRD waveguide.It means that wider bandwidth and higher integration can be obtained.The simulation results and measurement data verify the novel transition.

Key words: printed circuit board, slot line, substrate integrated nonradiative dielectric waveguide
