This work presents an overview of microwave components based on air-filled SIW technology. These devices has been modified by properly placing some dielectric substrate material inside them. This allows to achieve partial component size reduction and to obtain new frequency behaviors. The article includes a slab transmission line with wide single-mode bandwidth, a high efficiency leaky-wave antenna, a compact dual-mode cavity filter and a microfluidic sensor. Some of the components have been designed leveraging the flexibility of additive manufacturing technologies, which allow for the selective control of the density of the dielectric material and for the fabrication of complex topologies such as pipes.
