ABSTRACT:
The invention concerns a patch antenna (20) for a small-sized portable electronic instrument comprising a radiating element (21) separated from a ground plane (23) by a dielectric (22) and comprising feed (25) and ground (26) conductors for electrically connecting said radiating element and said ground plane (23) respectively, to an electric module (6). The ground plane (23) consists of a stamped metal plate including at least a folded foot (26a, 26b) outside said ground plane and directly connecting said ground plane (23) to said electronic module (6), said foot (26a, 26b) forming said ground conductor (26) of the antenna.
