摘要
Abstract
TE2i-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 Teai-mode coupling. On the basis of analysis and numeric simulation, one 8-arm TE2i-mode coupler with 20-hole array is designed and its prototype is fabricated. A good agreement between theoretical and experimental results confirms the validity and the accuracy of the system design. Within fi ± 0.3 GHz range interested, the coupling of TE21 mode is less than 2 dB(8 dB in 8-arm) and the isolation of Ten mode is greater than 40 dB, which is up to the expected indexes.关键词
