Abstract: A ball (1) for use in a sporting activity can comprise a body having an electrical circuit (21) on a flexible substrate (20) received therein. The electrical circuit (21) comprises a dipole antenna (26) integrally formed with the electrical circuit (21) on the flexible substrate (20). The dipole antenna can comprise two arms (23, 24) each folded in a semi-circular shape.

Abstract: The invention relates to a locating device for locating an object. The invention also relates to a system of a locating device and of an object, a golf accessory and a golf ball. The locating device comprises a first directional receiver so as to receive the emitted signal. The first directional receiver is directed with a first main axis in a first direction. The reception unit is also provided with a second directional receiver with a second main axis, and also with a third directional receiver with a third main axis. The second and the third main axis are positioned transversely with respect to the first main axis. The locating device is configured for processing the signals received by the at least three directional receivers so as to obtain a location property of the object.
