Micro-additive fabrication of 38 GHz resonators and filters

A new additive micro fabrication process for cavity resonator and band-pass filters is presented. 195 μm thick 3D air-filled components are fabricated operating at 38 GHz cavity resonator and two-pole band-pass filter. This paper presents a complete characterization of these components, with accurate simulation models. These models can be used to compute the losses in the component, and next improve them.
