Innovative SIW components on paper, textile, and 3D-printed substrates for the Internet of Things

This paper presents an overview of the recent achievements in the developments of novel components and innovative materials for the future Internet of Things (IoT). The development of substrate integrated waveguide (SIW) components and antennas is discussed, with particular emphasis on the use of paper substrates for eco-friendly wireless systems, textile for wearable components, and 3D-printed substrates for fully-3D cost-effective structures. Several prototypes are presented to validate the proposed fabrication technologies and show the potential of integrated microwave systems for IoT applications.
