Design of Tri-Band Textile Fractal Antenna Using Three Different Substrate Materials for Wi-Fi Applications

Abstract

The purpose of this study is to embed an antenna on very thin textile materials. A rectangular Fractal Antenna is chosen for this application. This antenna radiates for three different frequencies viz. 2.4 GHz, 4.2 GHz, and 5.9 GHz. The substrate materials used for the three antennas are Poly Viscous, Poly Cotton, and Linen which are easily available. Instead of using traditional method applying copper plate or copper layer on substrate material, a simple process of pasting carbon conductive ink on substrate materials is used. On each textile antenna above mentioned frequencies are radiated. Performance parameters of all three antennas are simulated and matched with practical results. The optimum antenna having the best result is used for Wi-Fi applications.

Design of UWB MIMO antenna using lean wearable textile substrate for reduced SAR

“…A combination of the UWB–multiple input multiple output (MIMO) and textile antennas should provide the resolution for low power requirement; gain improvement, robustness. The techniques used in recent literature are broadly classified into the following categories: polarization diversity (Sumathi and Abirami, 2020; Ullah et al , 2020; Jamal et al , 2018; Laxman and Jain, 2021; Li et al , 2018); pattern diversity (Roy et al , 2019; Khajeh-Khalili, 2020; Gupta et al , 2020; Guptaa and Kumar, 2020; Biswas and Chakraborty, 2019); techniques with additional decoupling structure (Roy et al , 2020; Mao et al , 2020; Singh et al , 2020); and quasi-complementary (Kittur and Balaji, 2022; Badisa et al , 2022).…”

“…Wideband two-element textile MIMO antenna with T-shaped stubs and three rectangular rings used for reduce the interference, high isolation and better diversity gain (Singh et al , 2020). A triband fractal textile antenna is designed with different substrate material to improve high date rate in Wi-Fi application (Kittur and Balaji, 2022). A 3 × 3 AMC reflector textile antenna is proposed with improvement in gain and reduced SAR and back radiation (Badisa et al , 2022).…”
