The Internet of Things (IoT) shall be able to incorporate many different and heterogeneous end systems for the development of a plethora of digital services including everything from smart homes, smart health, smart retails, smart wearables, and connected toys to the industrial Internet of Things with smart agriculture, smart cities, smart factories, and the smart grid. IoT is an enormous opportunity, but it is not without challenges including reliable connectivity, a wide range of bands to support, and price pressures. With every physical thing being connected in IoT, wireless communication is the first choice of communication for Internet of Things node devices. Besides other required features, the choice of an antenna system will be a critical component of all these node end smart devices. Choosing the right antenna for an application presents a key design challenge. Creating effective antenna performance in IoT devices requires engineers to examine several factors including antenna size, from what is needed to what is possible, antenna shape, and placement. As IoT modules continue to shrink incorporating more wireless technologies, making space for antennas is becoming an increasingly significant challenge. Thus, IoT-module antenna designers face the restrictions of maintaining reasonable performance in ever-shrinking footprints and under extreme interference conditions.

The explosive growth of Internet of Things and smart industrial applications creates many scientific and engineering challenges that call for ingenious research efforts from both academia and industry for the development of efficient, cost-effective, scalable, and reliable antenna systems for IoT. This special issue brings together scholars, professors, researchers, engineers, and administrators resorting to the state-of-the-art antenna systems and technologies to significantly improve the field of IoT and its applications like smart industrial market/industry applications.
