摘要

ABSTRACT In this article, a novel textile jeans antenna is introduced that can cover range of frequencies from 3.85 to 14.58 GHz with a return loss of −23.02 dB at its lower working frequency of 4.8 GHz. To perform the simulation, the antenna is designed on the jeans substrate with of 1.7 and size of 43.6 × 49 × 1 mm 3 (0.7 λ 0 × 0.8 λ 0 × 0.016 λ 0 at frequency 4.8 GHz) Moreover, for improving bandwidth, defective ground structure (DGS) is used which provides a wide bandwidth range of 116.44%. The peak gain is found to be 4.5, 4.4, and 4.3 dBi at 4.8, 8.98, and 13.45 GHz, respectively. However, the efficiency is found more than 70% in operating band. The proposed antenna has omni‐directional pattern for radiation and has good bending and wet characteristics suitable for IoT application like Wi‐Max and AI, IoT devices such as automotive and robotics. The specific absorption ratio at 4.8 GHz is found to be maximum near the feed point which is 0.00596 W/kg for 10 g of tissue which is low as compared to standard value of 1.6 W/kg for 10 g of tissue.
