| 摘 要： | 以耦合波理论为基础,在考虑了圆波导壁厚对耦合的影响以及耦合小孔间相互影响的情况下,设计出相应的TE21模耦合器结构和耦合器样机。样机实测特性指标与数值计算结果吻合,在f0±0.3 GHz范围内,耦合度小于2 dB(单臂小于8 dB),抑制度大于40 dB,达到预期的技术要求。

| Abstract: | The TE21-mode tracking coupler is used in a geostationary satellite auto-tracking and transmitting feed antenna.Based on the coupling wave theory,the diameter of each coupling hole is re-calculated according to the voltage coupling formula of small hole to counter the negative effects of wall thickness on TE21-mode coupling.On the basis of analysis and numeric simulation,one 8-arm TE21-mode coupler with 20-hole array is designed and its prototype is fabricated.A good agreement between theoretical and experi... |
