这封信展示了第一个完全3d打印的微波可变移相器。介绍了一种三维可打印介质瓣金属管矩形波导可变移相器的设计方法。ABS建筑材料在10 GHz下的介电常数为2.34，损耗正切仅为0.0015。给出了预测和测量性能，表明在10 GHz时最大相对相移为142°，整个x波段相对相移几乎均匀，差相群延迟变化很小。
This letter presents the first fully 3-D printed microwave variable phase shifter. The design methodology for a 3-D printable dielectric flap metal-pipe rectangular waveguide variable phase shifter is described. The ABS building material was independently characterized, revealing a dielectric constant of 2.34 and loss tangent of only 0.0015 at 10 GHz. The predicted and measured performance is given, demonstrating a maximum relative phase shift of 142° at 10 GHz, with a near uniform relative phase shift across the whole of X-band and a low variation in differential-phase group delay.
