文章基于负折射电路原理,提出利用集总电容、电感加载构造得到宽带90度功分移相器,并提出了利用该功分移相器结合翻转容性馈电结构来拓展宽微带天线的阻抗带宽和轴比带宽的方法.设计并制作了工作频率为1.375GHz、轴比小于3dB的相对带宽为52.37%、在此频带内驻波比小于2的天线.

Based on the negative refraction circuit theory,a novel broadband Power Divider and Phase Shifter which is con-strutted by conventional transmission line with lumped-element series capacitors and shunt inductors is proposed in this paper. And the realization method of broadening impedance and axis ratio bandwidth is analyzed. A microstripe antenna which central frequence is 1,268GHz is designed, and the axis ratio bandwidth achieved 52.37percent. The VSWR is below 2 in the AR bandwidth.
