<p><span>In this article, the dual band is achieved with J-slot on rectangular Textile antenna on Jeans fabric as substrate. It resonates at the 2.4 GHz and 5.4 GHz of Wireless Body Area Network (WBAN) bands. The novel J-slot Electromagnetic Band Gap (EBG) array consists of 2x2 elements. It is used as superstrate of J-slot textile antenna for Specific Absorption Rate (SAR) reduction and gain enhancement. The Reflection coefficient and VSWR of dual band textile antenna are simulated and measured with and without human body<strong>.</strong></span></p>
In this paper, Rectangular Electromagnetic Band Gap (EBG) Structure and multiple slots on patch are proposed to improve the gain and bandwidth of the Textile antenna. The EBG structure is sandwiched between the patch and the ground plane. A Single band textile antenna has a resonant frequency of 5 GHz used for IEEE802.11a Wireless Body Area Network (WBAN) applications. Four slots are created on the hexagonal patch, so the patch shape appears like WiFi symbol. For this antenna, jeans fabric is used as substrate. The design is simulated using HFSS software.
The performance and analysis of three different substrate fabrics such as cotton, felt, and jeans for the wearable textile antenna are presented in this paper. The dielectric constants of three fabrics are between 1 and 2 only. The two arcs and one circle slot are created on a hexagonal patch. The Wi-Fi shape wearable textile antenna is designed for WBAN (Wireless Body Area Network) applications. The simulated results of the radiation pattern return loss and VSWR of the aforementioned wearable textile antennas with three different substrates are evaluated, and the same is presented at the end. The Wearable antenna has been designed using HFSS software.
