The use of 3D printers and plating is an effective method for prototyping expensive high-frequency components easily and at low cost. The purpose of this study is to monolithic mold a millimeter-wave waveguide bandpass filter (BPF) with a fine structure. We propose a new structure which is suitable for the 3D printing, and introduce the FDTD method (finite difference time domain method) and µGA (micro genetic algorithm) in its design. It is confirmed from the prototype and measurement results that the filter properties are obtained with the proposed structure.
