摘要: Two iris bandpass filters implemented by three-dimensional (3D) printing technology for millimetre-wave applications are demonstrated the first time. The designed at E-band (60-90 GHz), and fabricated selective laser melting using CuSn15 alloy powder. A shifted passband increased insertion loss observed, which is caused fabrication tolerance of dimensional control surface roughness. Methods to compensate proposed design procedures provided. presented results prove great potential 3D millimetre wave applications.
