GSM fabric antenna for mobile phones integrated within clothing

Present day products utilize the mobile phone´s relatively small built-in antenna. However the close proximity of the antenna to the user´s body leads to extensive signal losses. Building the antenna into the clothing would allow a much larger antenna to be constructed that incorporates a large ground plane to isolate the user from the antenna´s fields. Antenna construction using fabric technology enhances user comfort by permitting the antenna to be light, breathable and flexible. This paper describes how a fabric mobile phone antenna may be incorporated within a new range of garments.
