Abstract: This work presents the design and performance evaluation of a compact, flexible, circularly polarized wearable antenna based on a leather substrate for body-centric wireless communication applications. The antenna is fabricated on a 30 × 20 × 1.5 mm³ leather substrate, selected for its mechanical robustness, flexibility, and stable dielectric characteristics suitable for wearable integration. The proposed antenna operates at multiple frequency bands, namely 2.29 GHz, 3.65 GHz, 4.75 GHz, and 5.8 GHz, enabling compatibility with ISM, WLAN, WiMAX, and emerging 5G communication systems. It exhibits excellent impedance matching with reflection coefficient (S11) values below –10 dB across all resonant frequencies, ensuring efficient power transfer and minimal signal loss. Circular polarization is achieved with axial ratio values less than 3 dB, providing reliable signal reception and reduced polarization mismatch. The antenna demonstrates high radiation efficiency in the range of 86% to 92%, along with stable gain characteristics across the operating bands. The compact geometry and optimized structure contribute to consistent electromagnetic performance. The use of a leather substrate enhances durability, flexibility, and user comfort in wearable environments. The multiband capability supports seamless integration into various wireless communication systems. The design ensures stable and efficient operation in compact and constrained conditions. Overall, the proposed antenna achieves an effective balance between size, flexibility, multiband functionality, and high efficiency. Therefore, it is well suited for applications in Wireless Body Area Networks, Internet of Things systems, and next-generation wearable communication devices
