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 $ϵ_{r}$ of 1.7 and size of 43.6 × 49 × 1 mm³ (0.7λ₀ × 0.8λ₀ × 0.016λ₀ 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.

本文介绍了一种新型的纺织牛仔天线，其工作频率为4.8 GHz，覆盖范围为3.85 ～ 14.58 GHz，回波损耗为- 23.02 dB。为了进行仿真，天线被设计在带有御柱的牛仔基板上 $$ {\epsilon}_r $$ 尺寸为43.6 × 49 × 1 mm3 (0.7λ0 × 0.8λ0 × 0.016λ0，频率为4.8 GHz)，为了提高带宽，采用了缺陷接地结构（DGS），提供了116.44的宽带宽范围%. 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.

期刊介绍： Prediction through modelling forms the basis of engineering design. The computational power at the fingertips of the professional engineer is increasing enormously and techniques for computer simulation are changing rapidly. Engineers need models which relate to their design area and which are adaptable to new design concepts. They also need efficient and friendly ways of presenting, viewing and transmitting the data associated with their models. The International Journal of Numerical Modelling: Electronic Networks, Devices and Fields provides a communication vehicle for numerical modelling methods and data preparation methods associated with electrical and electronic circuits and fields. It concentrates on numerical modelling rather than abstract numerical mathematics. Contributions on numerical modelling will cover the entire subject of electrical and electronic engineering. They will range from electrical distribution networks to integrated circuits on VLSI design, and from static electric and magnetic fields through microwaves to optical design. They will also include the use of electrical networks as a modelling medium.
