The antenna comprises a magnetic core (2), three windings (31, 32, 33) wound around the magnetic core (2) and an electrically insulated base (1) on which the magnetic core (2) wound with these windings (31,32,33) is arranged. The insulated base (1) includes metallic tabs (121 . . . 128) electrically connected to said windings (31, 32, 33) and the base (1) has a bottom surface with electrically conductive plates (131 . . . 138) with connection to the metallic tabs (121 . . . 128) and providing a layout for a SMT mounting, The antenna comprises an electrically insulated cap (4), having an upper surface (4U) including a metallized surface high frequency coil (42) working as a HF antenna and a side surface (4S), two ends (411, 412) of the coil (42) being arranged on the side surface (4S) for connection to the metallic tabs (121 . . . 128) of the electrically insulated base (1).
