Abstract:
In this paper, Wearable antenna for off- and on-body
wireless communications is introduced. It introduces to operate at
ISM band for medical applications and WLAN bands. The
proposed antenna not only has a compact size but also it supports
a low SAR radiation at the operating frequency 2.4 GHz. It
consists of a meander line and an electromagnetic band gap
structure (EBG). In order to cover the low frequency at 2.4 GHz, a
meander line is utilized due to its compact size. The solution stems
from the use of EBG structure which widens the band and to
reduce the maximum SAR. The subject of human body–antenna
interaction has also been studied. The operating bands ranges are
(2.3-2.55 GHz), (3.1-3.3 GHz), (3.78-3.9 GHz), and (4.7-5.6 GHz).
The antenna size is 23.5×30×1.2 mm3
