摘　　要：提出了一种新型的宽带平面魔T结构。对传统的混合环结构(1800电桥)进行了改进,引入了槽线与微带过渡结构。为了展宽频带,采用了三叉指形转换单元和四分之一波长阻抗变换结构。测量结果表明:该魔T的相对带宽可以达到62%,在工作带宽(2.6Ghz—5.1Ghz)内,插入损耗小于1dB,相位特性良好。A novel broadband planar magic T is proposed. It is based on the traditional hybrids configuration. The transition of microstrip -slotline is introduced. In order to broaden bandwidth, junctions of stubs and the transformation structure of one quarter of wavelength are applied to this novel magic T. The operation bandwidth of magic T is more than 62% , which is from 2.6 GHz to5.1Ghz. The insertion loss is less than 1dB and it has good phase characteristics.
