Problems solved by technology

[0007] Another drawback of these solutions is the overall aesthetic appearance of the electronics
In addition, although relatively compact, the various antenna configurations employed make the instrument have a prominent part that would be cumbersome and uncomfortable when worn on the user's wrist

Embodiment Construction

[0036] Figure 1 shows a plan view of a portable electronic instrument according to the invention, generally indicated by reference numeral 1 and advantageously in the form of a wristwatch. The watch 1 is equipped with an antenna 20 electrically connected to an electronic module 6 ( FIG. 2 ) arranged inside the watch. In this example, antenna 20 is used to receive radio frequency signals transmitted by one or more different transmission sources. More particularly, this antenna is used to receive satellite navigation and positioning signals such as GPS signals (Global Positioning System) from the American system NAVSTAR, or other similar satellite positioning signals such as the Russian system GLONASS or the future European satellite positioning system GALILEO .

[0037] In addition, the invention is also applicable to any type of portable electronic device comprising an antenna for receiving and / or transmitting radio frequency signals and is therefore not limited to a single a...

Abstract

Portable electronic instrument of the watch and bracelet type having in a casing (2) a metallic housing (4) with base and lateral walls and sealed window opening for a glass (3). The antenna (20) rests on the exterior face (7a) of metallized plastic glass support (7). A circular fitting ring (8) is fitted between the support and the base. An electronic module (6) and a display unit (5) are enclosed between the support and the fitting, both of which form a removable sub- assembly. The support is electrically connected to the metallic housing. A protective cover (9) made from a dielectric material fits over the support and covers the antenna. The fitting is fixed in the base (4a) by fixings. The instrument includes:- (a) a housing enclosing an electronic module and display unit; (b) a glass fitted on the housing; (c) an electrical energy supply source (10) located in the housing feeding the module and display, and; (d) a radio frequency receiving and / or transmission antenna electrically connected to the module.

Description

technical field [0001] The present invention generally relates to a portable electronic instrument comprising, inter alia, an antenna for receiving and / or transmitting radio frequency signals. In particular, the invention relates to a portable electronic instrument, such as a watch, intended to be worn on the wrist of a user and comprising an antenna for receiving satellite navigation and positioning signals or GPS signals. Background technique [0002] Various portable electronic instruments including antennas for receiving and / or transmitting radio frequency signals have been proposed. One of these solutions includes, for example, winding a dipole antenna inside the housing, the dipole antenna being formed, for example, by forming a printed via on a flexible dielectric substrate. Due to the specific configuration of the antenna, this solution is likewise unsuitable if it is desired to manufacture an instrument with a housing made of metallic material which significantly i...
