| 摘 要： | 介绍了由槽线、共面波导和气桥构成的超宽频带共面魔T。采用有限元法在10GHz对魔T作优化分析计算;结合给出的新型槽线与标准同轴连接器之间的转换形式,最终得到实际魔T。测试和分析计算结果显示,这种共面魔T具备超宽频带特性;魔T在1GHz～11GHz(18GHz)频带内,匹配、耦合度及隔离度具有良好性能。

| Abstract: | An ultra-wide-band uniplanar magic T consisting of coplanar wave guides, slot lines and air bridges as mode filters is studied. After the magic T is optimized using the finite element method at its working center frequency and the transition of the slot-line to standard coaxial connectors introduced is used, the real magic T is satisfied. The experiment results of the performances for matching, coupling and isolation show that the working frequency range is 1?GHz to 11?GHz (18?GHz) and the characters of this uniplanar magic T are ultra-wide-band and it can be widely used in wide-band systems. |
