This paper presents the design and first experimental results of a very compact Ku-band bandpass filter for high power satellite applications. The filter was designed and simulated using the Ansys HFSS and Mechanical simulators.
Proposed as part of an ESA ARTES Advanced Technology project, the filter is based on dielectric loaded combline resonators.
Several dielectric materials were considered and two models of the same filter are presented in this paper.
The geometries and materials were chosen to improve the performance in terms of power-handling and multipactor up to 150 W continuous wave of input RF power. Barrel-shaped metal cavities and high-permittivity ceramic materials were
mixed to minimize volume occupancy while maintaining high unloaded Q-factor values (>4500).
CASE STUDY
Pipistrel, an aviation and aerospace company based in Slovenia, chose ESTECO technologies to design the propeller for a highly efficient, hybrid-electric aircraft.
