Abstract

The aim of this work is to fabricate and characterize a very compact branch-line coupler at the UHF band, where the wavelength is critical for miniaturization. In order to do this, the advantages of a 3D-printed electronics manufacturing process developed in former work demonstrated the usability of helical-microstrip transmission lines and allowed the materialization of a new folded topology for hybrid couplers. The design methodology and the manufacturing process have been described. A conventional hybrid coupler has been also designed, manufactured and characterized in order to compare dimensions and model simulation and prototype characterization results in terms of the scattering parameters.
基于螺旋微带传输线的紧凑3d打印折叠分支混合式耦合器
这项工作的目的是在UHF波段制造和表征一个非常紧凑的分支线耦合器,其中波长对小型化至关重要。为了做到这一点,在以前的工作中开发的3d打印电子制造工艺的优势证明了螺旋微带传输线的可用性,并允许实现混合耦合器的新折叠拓扑。描述了设计方法和制造过程。本文还设计、制造了一种传统的混合耦合器,并对其进行了表征,以比较其散射参数的尺寸和模型仿真及原型表征结果。
