A Fully Automated Robotic System for Tuning Optimization of RF Cavity Filter

Journal of Field Robotics, Volume 42, Issue 6, Page 2826-2852, September 2025.
ABSTRACT The advancements in radar systems, electronic warfare, and telecommunication industries have generated a substantial demand for microwave filters. Among these, cavity filters have conventionally served in transmitters and receivers, facilitating the passage of desired signals in the passband while effectively rejecting harmonics and spurious ...

Mechanical Tuning of Air‐Filled Substrate Integrated Waveguide Cavities by Employing Dielectric Rods

Microwave and Optical Technology Letters, Volume 67, Issue 8, August 2025.
ABSTRACT This study presents a simple method to obtain tunable cavity resonators in air‐filled substrate integrated waveguide (AFSIW) technology. It is based on the insertion of a dielectric rod from an opening placed on a side of the SIW cavity, whose resonance frequency is varied by changing the penetration depth of the rod. To avoid power leakage, a
