摘　　要：基于人工电磁材料开环谐振器,提出了一种结构紧凑的新型宽带微带功率分配器。通过在微带线上加载开口谐振环(SRRs)单元,使其在某个频段内呈现色散性质即支持后向波传播,从而实现宽带特性。该结构可简单地通过改变开环谐振器结构参数来调节功率分配器中心频率。测试结果表明,该功分器具有体积小巧、损耗低、易制作并方便与其他电路集成等优势。A novel broadband microstrip power divider based on artificial line implemented by means of split ring re-sonators （SRRs） is presented . The topology is consisted by microstrip line sections with SRRs etched on the top. By these means, a dispersive transmission medium supporting backward （or left handed） wave propagation within a certain frequency band around the split-ring resonance is obtained. To illustrate the potentiality of the approach two SRR-cell based power di-viders were designed and fabricated. A compact broadband power divider is designed to validate the practical use of the new unit cell. The experimental results show that the proposed power divider shows advantages of compact size, low loss, easy fabrication and integration with other circuit.
