摘要：
This paper presents a fifth-order waveguide bandpass filter fabricated by 3D printing technology. The filter has a centre frequency of 180 GHz, a fractional bandwidth FBW=11% and a Chebyshev filtering response. The filter is fabricated by the micro laser sintering process and it is made as an all-metal monolithic device. Two samples of the specified filter are made of stainless steel and tested. The measured results are encouraging and demonstrate the excellent reproducibility of the fabrication process.
