Enhancement of Gain and Bandwidth using EBG Structure for Textile Antenna

Abstract

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.

Analysis and implementation of shorting pins in microstrip patch antenna for SAR reduction

“…Various techniques have been presented in the literature to reduce the SAR in handheld devices [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. It can be inferred from the previous works that one of the straightforward and uncomplicated ways to lower the SAR value is by increasing the distance between the antenna and the human body.…”
