Abstract: The deployment of ultra-wideband (UWB) technology offers enhanced capabilities for various Internet of Things (IoT) applications, including smart cities, smart buildings, smart aggregation, and smart healthcare. UWB technology supports high data rate communication over short distances with very low power densities. This paper presents a UWB printed antenna design with multiple input and output (MIMO) capabilities, specifically tailored for Routed Satellite Sensor Systems (SRSS) to enhance IoT applications. The proposed UWB printed antenna, designed for the 2–18 GHz frequency band, has overall dimensions of 14.5 mm x 14.5 mm, with an efficiency exceeding 70% and a gain ranging from 2 to 6.5 dB. Both simulated and measured reflection parameters (|S11|) at the antenna input show strong agreement. Furthermore, a compact MIMO system is introduced, featuring four closely spaced antennas with a gap of 0.03λ, housed in a 60 mm x 48 mm module. To minimize coupling effects between the antennas, the design incorporates five Split Ring Resonator (SRR) elements arranged linearly between the radiating elements. This arrangement achieves a mutual coupling reduction to -35 dB at 8 GHz, compared to -20 dB isolation in systems without SRR. The results demonstrate that the proposed MIMO antenna system offers promising performance and meets the requirements for effective space communication within satellite sensor networks.
