Abstract: This master’s thesis treats the obtention of a proof of concept of a textile antenna able to transmit pertinent data such as electrocardiograms. Those antennas were fabricated using methods of chemical metalization. Particularly, the chemical reduction of silver and copper and the electrodeposition of copper was used to metallize capillaries made of different materials. These capillaries have been configured as filar antennas to obtain half-wave dipoles and loop antennas. A parallel work was done to develop the leaky feeder known as «Leaky Coax» (LCX) that consist in a coaxial cable of which the outer metallic layer is opened in windows to let the electromagnetic field leak out. There exist numerous potential applications to textile antennas, for example : clothesintegrated Global Positioning System (GPS) setups for the localization of kidnapped people, remote medical surveillance, or transmission of biometric data for cutting-edge sportive training. To demonstrate the viability of biometric applications, we decided to amplify a cardiac signal and to transmit it via the 2.4GHz Industrial, Scientific and Medical (ISM) frequency band that is also used for Wi-Fi networks.
