A 3D-printed X-band evanescent mode waveguide filter based on pixelization strategy is proposed in this letter. The uniqueness of the filter lies in the exploitation of the evanescent mode waveguide in conjunction with a 3D-printed dielectric pixelated structure. The crucial advantage of this approach is the fact that the dielectric pixelated structure located in a waveguide is not metal coated, so the fabrication process is easier. The proposed filter is manufactured using the fused deposition modeling 3D print technology. Its measured transmission coefficient in the passband is approximately -2 dB, and the reflection coefficient is below -19 dB.
