Various fabric antennas for incorporation in garments have been around since 2000 (early example). The topic has been revisited by scientists at Ohio State University who can use high precision embroidery to generate antennas in the microwave frequency. The embroidery uses conductive thread to form the antenna pattern. It is envisaged that by clipping our phone or other devices into our clothes we will get better reception. This makes a lot of sense, given that our clothes have a large surface area which can be used to collect useful wireless signals (like you cell call or data). The only issue is deformation changing the frequency, so the placement in the garment will be critical to effective operation.
