| [摘要] |
| 本文在分析新型传输线-微带加载插入介质波导(M-IDG)基本特性的基础上，用FDTD法仿真设计了小型、超宽带衰减器。电路尺寸分5．1×25mm２和5．1×40mm2两种。对于10dB衰减器，工作频带0．5～18GHz内衰减起伏小于1.0dB；30dB衰减器，在2．0～18GHz带宽内，衰减起伏小于2．5dB。实测结果与FDTD仿真结果基本吻合。 |

| The basic properties of the microstrip-loaded inset dielectric guide (M-IDG) are analyzed by FDTD method, then this kind of ultra wide band attenuators are implemented by FDTD simulation. There are two kinds of the circuit sizes--5. 1×25mm2 and 5. 1×40mm2. For 10dB attenuator,the fluctuation of attenuation is less than 1.0dB within 0. 5～18GHz bandwidth. For 30dB attenuator,the fluctuation is less than 2. 5dB within 2.0～18GHz bandwidth. The measurement data are in agreements with the results of FDTD simulation. |
