Antenna device for timepiece

An antenna device used in a communication system of a timepiece, the antenna device comprising:

• a substrate;
• a first antenna formed on said substrate and having first and second strands each having a proximal end and a distal end, and extending in parallel between the proximal and distal ends thereof, the first and second strands being connected at the proximal ends thereof and separated at the distal ends thereof;
• a second antenna formed on said substrate and having third and fourth strands each having a proximal end and a distal end, and extending in parallel between the proximal and distal ends thereof, the third and fourth strands being connected by the distal ends thereof and separated at the proximal ends thereof;
• an electrical junction link joining the proximal ends of the first and third strands;
• a connection portion configured to be bent relative to said electrical junction link, and including a conductive connection, which is connected to the electrical junction link and including an electromagnetic shielding of said conductive connection.
