“…Similarly, ellipsoidal resonators characterized by elliptical cross‐sections are employed to break the symmetry of the sphere. And a shape deformation technique 17 is also employed to further shift spurious resonances away. This results in a novel cavity termed the deformed ellipsoidal resonator, as depicted in Figure 2A.…”

“…Among various 3D printing technologies, stereolithography (SLA) stands out as a preferred choice for fabricating waveguide filters due to its high accuracy and low surface roughness. Three‐dimensional printed filters with integrated waveguides (standard H ‐ or E ‐plane bends, or 90° twist) have been reported 11–18 . Three‐dimensional printed filters with twists have been demonstrated through a continuous twisting configuration 11 or a cascading configuration involving multiple steps 12 .…”

This letter presents compact waveguide variable bends incorporating integrated bandpass filters. Two designs have been demonstrated within X‐band (8.2–12.4 GHz) range, using three‐dimensional stereolithography printing and copper plating. The first design utilizes coupled elliptical resonators, while the second employs coupled deformed ellipsoidal resonators. These designs provide both filtering functionality and complex waveguide routing simultaneously, thereby leading to a reduction of total size and loss. This facilitates the design of compact, low‐loss, and multifunctional integrated subsystems. The measured responses (without any tuning) of both waveguide variable bends exhibit excellent performance, with averaged insertion loss of 0.59 and 0.57 dB, and return loss better than 11.9 and 19.8 dB throughout the passband, respectively. Good agreements between the simulated and measured results of the prototype devices successfully validate the feasibility and practicality of the proposed concept.
