Abstract

The increasing demand for robust and scalable wireless infrastructure in smart city has highlighted the potential of utilizing existing building materials as functional components in communication systems. This study investigates the feasibility of embedded metallic structures, specifically steel elements such as galvanized hollow steel and rebars as passive monopole antennas for sub-GHz Internet of Things (IoT) applications. Focusing on the 700 MHz frequency range, analytical modeling was conducted to examine the electromagnetic behavior of monopole configurations formed by structural elements in a concrete medium. Key parameters such as resonance length, impedance matching, and radiation characteristics were derived based on standard antenna theory. The simulation results confirm that selected metallic structures can support monopole resonance with acceptable return loss and bandwidth performance for IoT communication. The integration of antenna functionality into structural elements opens new possibilities for cost-efficient and unobtrusive wireless systems in smart city environments.
