Abstract

This contribution deals with the main parts of the textile-integrated transmitting unit, a transmitter and an antenna, operating in the ISM 5.8 GHz band. The transmitter is based on commercially available WLAN UART Serial Port OWS451 and it is controlled via the UART interface by microprocessor ATmega328. The antenna is based on the circular ring-slot concept and it is able to provide monopolar radiation pattern to ensure maximum coverage of the unit. The unit will be integrated in a seat cover and it will transmit the telemetry of sensors integrated in the seat (temperature, pressure…).
