Fractal Shape Dual-Band EBG integrated Textile Antenna

Abstract

In paper, a modified design and response of fractal shape dual-band Electromagnetic bandgap (EBG) integrated textile antenna is detailed. Designed antenna works on the GSM and ISM bands with frequency 1.8 GHz and 2.45 GHz respectively. Antenna prototype is made up of common clothing fabric like jean and adhesive copper tape. The paper contains software simulation on Ansoft HFSS (high-frequency structure simulator) and hardware model of the antenna with EBG and without EBG. Required results are found even after changes in the structure of EBG. The design of monopole antenna, bandgap structure and their integrated is presented. The $3 \times 3$ bandgap array structure is used to reduces the back radiation into human body over 16 dB.
