| 摘 要： | 为扩展带状线小室工作带宽，基于标准IEC61967-8对EM601-6型带状线小室进行改进，提出芯板开缝的方法扼止横向电流，在三维电磁仿真软件CST中建立了带状线小室的三维仿真模型，并计算出改进后带状线小室的S参数和电压驻波比（voltage standing wave ratio, VSWR）.计算结果表明，芯板开缝的带状线小室的上限可用频率由6 GHz提高到了7 GHz.根据仿真结果加工制作的实物，虽然S21和S11比仿真结果差，但是在标准要求的范围内工作频段可由0～6 GHz扩展到0～7 GHz.

| Abstract: | In order to expand the working bandwidth of the IC-stripline, based on the standard IEC61967-8 to improve on the EM601-6 IC-stripline, this paper analyses the working principle and design principle of the IC-stripline, and calculates the size of the septum under the condition of good impedance matching. A method of chopping the transverse current is proposed and a 3D simulation model of the IC-stripline cell is established in the 3D electromagnetic simulation software (CST). The S-parameter and voltage standing wave ratio (VSWR) of the improved IC-stripline are calculated and the calculation results show that the usable frequency of upper limit of the IC-stripline with the slotted septum is increased from 6 GHz to 7 GHz. Although the return loss and insertion loss of the manufactured IC-stripline cell are worse than the simulation results, the working bandwidth is increased from 0?6 GHz to 0?7 GHz within the range required by the standard. |
