Monolithic 3D printed waveguide filters with wide spurious‐free stopbands using dimpled spherical resonators Open
Employing a family of dimpled and slotted spherical resonators, and a set of X‐band waveguide bandpass filters (BPFs) is presented in this study. The resonators originated from spherical resonators with depression (hence, dimples are forme…
