Helix antenna printed multiband slot

or less helical antenna comprising a helix formed of at least two strand conductors (201,202) radiating, at least one of said conductive strands (201,202) extending into at least two sub-strands (24) separated by a slot ( 22) of height (23) and of predetermined width, said slot (22) being connected at at least one point to a current peak (30), so as to permit multi-band operation of said antenna.
