  • Armored magnetic field antenna in printed circuit
    Patent number: 6215455
    Abstract: A shielded magnetic-field antenna has at least one turn of a metallic element and metallic tubular shielding positioned around the element. The turn (3a) is produced in a printed circuit on a card made of insulating material (4a). The shielding has two open rings (5a, 6a) each produced in a printed circuit and disposed respectively on a bottom card (9a) and a top card (10a) made of insulating material. The cards are assembled by gripping the turn between the top and bottom cards. A plurality of metallic vias (7a, 8a) connect side edges of the two rings.
