本文报道了一类新的宽带和全3D打印的$E$平面同轴到波导的过渡和单片3D打印波导魔术T的过渡的基础上。该过渡由一段空气填充的矩形同轴传输线（TL），放置在两个宽带同轴到波导探针过渡。它用于连接魔T的求和端口和波导T形结。过渡区的引入将魔T的所有波导臂重新定向到$E$平面中。一些$X$波段的原型所提出的过渡和魔术T的设计和实现。采用基于聚合物的增材制造和铜电镀技术来单片制造每个原型。过渡和魔术T表现出宽带和低损耗特性，从8.2到12.4 GHz的测量性能与模拟匹配良好。此外，功率处理能力（PHC），包括峰值PHC（PPHC）和平均PHC（APHC），魔术T的模拟评估，表明建议魔术T可以处理100 W的APHC。
This article reports on a new class of broadband and fully 3-D printed $E$ -plane coax-to-waveguide transition and a monolithically 3-D printed waveguide magic-T based on the transition. The transition is constructed by a section of air-filled rectangular coaxial transmission line (TL) that is placed between two broadband coax-to-waveguide probe transitions. It is used to interconnect the magic-T’s sum port and the waveguide T-junction. The incorporation of the transition reorients all the waveguide arms of the magic-T into the $E$ -plane. Some $X$ -band prototypes of the proposed transition and the magic-T are designed and implemented. Polymer-based additive manufacturing and copper electroplating techniques are employed to monolithically fabricate each prototype. The transition and the magic-T exhibit broadband and low-loss characteristics from 8.2 to 12.4 GHz with the measured performance well matched with the simulations. In addition, the power handling capability (PHC), including the peak PHC (PPHC) and the average PHC (APHC), of the magic-T is evaluated by simulations, showing that the proposed magic-T could handle 100 W of APHC.
