鱼刺型微带铁氧体环行器的频率特性
Frequency characteristic of fish-bone type microstrip ferrite circulators
摘要
Abstract
A fish-bone type microstrip ferrite circulator was designed and simulated using the 3D electromagnetic simulation software HFSS. The effects of the saturation magnetization Ms and the ferromagnetic resonance linewidth AH of the ferrite substrate on the frequency characteristic of the circulator were investigated. The results show that Ms has significant effect on the frequency characteristic of the circulator, and high reflection, high isolation and low insertion loss can be achieved for the circulator when a suitable Ms is employed. However, AH shows little effect on the frequency characteristic of the circulator and hence can be chosen from a wide range. When Ms= 47.8 kA/m and AH = 4.0 kA/m, the circulator exhibits an insertion loss of 0.17 dB, a reflection of 33.8 dB, an isolation of 48.6 dB, a standing wave ratio of 1.04, and a bandwidth beyond 300 MHz at the peak frequency of 3.8 GHz.关键词
