Estimating the term…
The present invention concerns a structure forming an antenna (10) intended for a portable unit of small volume, such as a timepiece, and including a radiating element (20) of substantially rectangular shape arranged at a determined distance from a ground plane and short-circuited with this ground plane by one (20b) of its ends (20a, 20b), the opposite end (20a) of said radiating element (20) being left free. According to the present invention, said structure (10) includes a case (11) forming an integral part of said ground plane and including at least a cover (12), a bottom (14), and a lateral wall (13b) facing which is arranged said radiating element (20), said case (11) forming a shielded housing able to accommodate all or part of an electronic circuit and/or other components of the portable unit. The present invention also concerns a timepiece incorporating the aforementioned antenna structure.
An antenna structure intended for a portable unit of small volume, and including a radiating element of substantially rectangular surface arranged at a determined distance from a ground plane and short-circuited with this ground plane by one of its ends, the opposite end of said radiating element being left free, wherein said structure includes a case forming an integral part of said ground plane and including at least a cover, a bottom, and a lateral wall, said radiating element being disposed laterally with respect to said case in-between said cover and bottom, the surface of said radiating element facing said lateral wall, said case forming a shielded housing able to accommodate all or part of an electronic circuit and/or other components of the portable unit.
A timepiece comprising an antenna structure including a radiating element of substantially rectangular surface arranged at a determined distance from a ground plane and short-circuited with this ground plane by one of its ends, the opposite end of said radiating element being left free, wherein said antenna structure includes a case forming an integral part of said ground plane and including at least a cover, a bottom, and a lateral wall, said radiating element being disposed laterally with respect to said case in-between said cover and bottom, the surface of said radiating element facing said lateral wall, said case forming a shielded housing able to accommodate all or part of an electronic circuit and/or other components of the timepiece.
