Development of dual-band wearable textile antenna for WLAN applications

Currently, antennas integrated in clothing are particularly interesting because they can employ conductive elements which are already in garments. Therefore, this study is spent on the design of a dual-band textile antenna for WLAN applications. Its dual-band is fed by a coplanar waveguide (CPW) configuration. The proposed antenna structure is produced from jute fabric and operates in the 2 to 2.57 GHz band & 4.26 GHz to 6.GHz band, at bands of 2.48 and 5.76 GHz, respectively, which cover the 2.4/ 5.2/ 5.8 GHz WLAN operating bands. The antenna looks like a double G form. The aim is creating two different paths for the current traversing the strips and thus creating two resonant modes depending on the electrical lengths of the strips. CST Microwave Studio Software was used to design and simulate the structure. Moreover, performances in terms of radiation pattern and gain are presented and discussed.
