In this study, design and characterization of a wearable monopole
antenna and metamaterial based electromagnetic band gap structure using
conductive textile was reported. The pure copper polyester taffeta fabric was
used as a conductive textile. The conductive textile based wearable antennas
have attracted considerable attention for body centric technologies due to the
ability of being integrated with clothes and easily worn. In this respect, the
reflection coefficients, radiation pattern, and surface currents for proposed
antenna were investigated and its performance was obtained. Then, we designed the
electromagnetic band gap structure (3x3 unit cell) and integrated the wearable
antenna with this structure. Finally, the specific absorption rate (SAR) values
for wearable antenna and integrated structure were analyzed. The SAR values of
wearable antenna and integrated structure were obtained as 17.4 W/kg and 0.329
W/kg, respectively. In addition, the electromagnetic band gap structure that
has 4x3 unit cell was designed and again the wearable antenna was integrated
with this 4x3 structure. Similarly, we obtained the SAR value of new integrated
structure as 0.241 W/kg. It was demonstrated that the integrated structures
have considerably favorable SAR value for human body. It can be used in many
wearable antenna applications with this low SAR value.
