Antenna coils emitting signals in a specified frequency band

The invention relates to a wire antenna for emitting device of periodic radio signals in a specific frequency band, said antenna comprising a plurality of wire turns. Two transmitting coils (221, 223) are separated by a coil (222) raised to a reference potential such as the masse.La turn (or) turn (s) range (s) to a reference potential can also be a (or more) winding (s) issue.
