This paper presents the design, fabrication, and comprehensive experimental evaluation of a compact textile antenna intended for mm-Wave 5G and wireless body area network (WBAN) applications. The antenna is realized on a flexible poly-cotton textile substrate with compact dimensions of 20 x 25 x 0.7 mm3, making it highly suitable for integration into wearable electronic platforms. The proposed antenna demonstrates stable impedance matching over the frequency range of 23.6-29.8 GHz, effectively covering key mm-Wave 5G bands. Radiation characteristics reveal a peak realized gain of 5.59 dBi with an overall radiation efficiency of approximately 82 %, indicating efficient power utilization despite the use of a lossy textile material. To assess mechanical robustness under practical wearable conditions, bending analysis was performed along both the X-axis and the Y-axis directions. The results confirm minimal performance degradation under mechanical deformation, validating the antenna’s flexibility and structural reliability. Specific absorption rate (SAR) tests on anthropomorphic hand and leg phantoms showed the highest values of 0.182 W/Kg and 0.246 W/Kg, respectively, which are well within current international safety limits. All these findings together support the safety, effectiveness, and adaptability of the antenna in the next-generation wireless communication systems of wearable gadgets. |
