| 摘 要： | 微带T 型功分器,是阵列天线馈电网络中最常见的微带功分器。它容易实现各种形式的复杂馈电网络,但是难以实现大功分比,主要原因在于其中一个支路的阻抗变换段是高阻抗线,现有加工水平很难实现。理论分析了通过单枝节网络等效替换高阻抗线的方法,可以实现大功分比。推导了单枝节网络的计算公式,并进行了仿真研究,最后利用该方法制作了一个功分器,实测结果和仿真数据吻合良好,证明了该设计方法的有效性和正确性。

| Abstract: | The design method of microstrip T-type unequal power divider with a high dividing ratio is discussed. And the design limitation of conventional T-type unequal power divider is illustrated; on this basis, we put forward the design method of T-type unequal power divider: to realize high power dividing ratio, the high impedance line is replaced by using single section equivalent network. It solves the practical processing problems of the high impedance line. The theoretical analysis and the test results show the validity and practicability about this method. |
