Modelling and Impact of 3D Print Inaccuracies on the Performance of Circular Waveguide Hybrid Coupler
关键词:
3D printing, circular waveguide hybrid coupler and electroless silver deposition摘要
Circular waveguide hybrid coupler operating over a frequency range of ISM 57-64 GHz, additively printed and metal plated using electroless technique is introduced. Effects of orientation of print and thickness of intricate structures on the performance of circular waveguide hybrid coupler are presented. The structure is printed using commercially available stereolithographic (SLA) printer. Circulatory system operated by a peristaltic pump is used for selective silver deposition of the hybrid coupler.
