Summary
Internet of Things (IoT) is a machine or asset with the intelligence behaviour used to communicate and update administration centre operations independently in real-time applications. The IoT applications require connectivity among the machines in many applications incorporating various transmission devices. Aside from modern communication standards, the right selection of a radiating device is crucial for all these node ends of intelligent devices. To determine the most appropriate radiator for wireless applications is still a challenging technical task. Federal Commission of Communication (FCC) approved a frequency band (3.1–10.6) GHz to be used without the requirement of any license. Ultrawide-band (UWB) technology has completed the standardisation in a standoff in shooting industrial sectors. UWB technology has gained considerable recognition across the last decade due to its large bandwidth, fast connectivity, saving power and low cost. Therefore, become technically beneficial for new application fields in wireless IoT connectivity. It is the main reason why the extensive research activities in the UWB IoT antenna community are noticeable in the UWB society. Metasurfaces are artificial structures that allow tailoring the propagation, scattering, and radiation of electromagnetic waves and have emerged as a candidate to fulfil the aforementioned requirements They have also been and are still being widely used in the microwave and antenna community for the realisation of multiple functionalities, such as absorption, filtering, reconfigurability, scattering control and polarisation handling.
