摘　　要：提出了一种微带负载线移相器的新设计方法 ,构建了一种蝶形负载线移相器 ,实现传统设计方法无法实现的小相移 (2 2 .5°,1 1 .2 5°,5.63°,… ) ,可用于卫星移动通信系统中的低成本高精度的相控微带天线阵 .This paper presented a new method of designing the microstrip load-line phase shifter. By constructing a papilionaceous loaded-line phase shifter, it can implement small phase shift (22.5°, 11.25°, 5.63°, ...) that can not be realized with the traditional methods. This type of phase shifter can be used as components of the low cost and high precision phased microstrip antenna array of satellite mobile communication system. The measured results of the developed prototype show that this new design method is correct and feasible.
