SIW components and antennas based on eco-friendly materials and technologies: State-of-the-art and future applications

Substrate integrated waveguide (SIW) technology represents a good candidate for the next generation of microwave and millimeter wave components and antennas. In particular, in the emerging area of the wireless sensors networks and the Internet of Things, SIW technology is the ideal candidate for the implementation of low-cost and eco-friendly wireless nodes. In this scenario, SIW components and antennas implemented by using unconventional materials and technologies (like paper and textile) open new interesting perspective for the development of green microwave systems.
