Technological advancements have fueled a growing demand for reliable mobile communication systems, highlighting the importance of wearable applications across various sectors, including biomedicine, military, and rescue services. This study underscores the crucial role of wearable antennas in addressing this increasing demand, with a specific focus on their design and development for Internet of Things (IoT) applications. The objective is to establish resilient communication links capable of operating effectively across diverse environments and weather conditions. Microstrip Yagi-Uda antennas, renowned for their directivity, lightweight construction, low profile, and cost-effectiveness, are the subject of investigation in this research. The study presents the simulated and fabricated design of a wearable microstrip Yagi-Uda antenna operating at 2.45 GHz. Three distinct substrate textile materials—100% polyester, cotton, and jeans—were examined and compared in the antenna design. Better performance was achieved with the 100% polyester substrate antenna design, boasting a gain of 8.8 dBi and a return loss of -33.9 dB at 2.45 GHz.
