Abstract :
This paper presents a novel conformal HF antenna concept. Soft magnetic materials are used to suppress currents on conductive surfaces in order to realise conformal HF antennas. The concept is verified by comparing predicted HF antenna characteristics to measured results. The efficiency of the conformal HF antenna is compared to a tuned whip and loop antenna. The conformal antenna shows superior performance above 15 MHz
