ABSTRACT:
The present invention relates to a system (100) and method for driving an antenna (118). The system (100) comprises a driving means (110, 112, 114) driving the antenna (118) with a driving signal. The system (100) further comprises a modulation means (102) having an input receiving a transmission data signal (106), a data identification means (122) identifying a level change in the transmission data signal (106) and controlling duty cycle of the driving signal (108). The data identification means (122) provides a timed increase of duty cycle of the driving signal (108) when the a level change in said transmission data is identified.
