Improving Parameters of Wearable Antenna Using EBG Structure

Abstract

This is need of the hour to design a low profile, low cost, acceptable Specific Absorption Rate value, high gain, high directivity and power efficient wearable antenna for the mentioned fields of wireless communication. This paper presents an optimal solution to address the issues in the field of wearable antenna. The Electromagnetic Band Gap (EBG) structure has been integrated with the patch on the flexible substrate of polyurethane. Different parameters of wearable antenna have been improved using the EBG structure. Gain of this structure has been improved from 5.32dBi to 7.17dBi, directivity has been enhanced from 6.69dBi to 7.82dBi and efficiency has been increased from 69% to 88.87%. The results have been shown in detail in this paper
