A metallic 3-D mask printed D-band iris bandpass filter

Abstract

This paper presents the design of a D-band (110–170 GHz) iris bandpass filter (BPF) for 3-D printing fabrication. Taking the advantage of the 3-D Mask Printing technology, the dimensional tolerance and surface roughness are much improved compared with the Selective Laser Melting (SLM) printed filter. The 3-D Mask Printed filter has a passband 144–146 GHz (|S11|<−18 dB) with in-band insertion loss than 0.6 dB. The measured results will be reported at the conference.
