More specifically, the present invention relates to a specific antenna structure that allows the portable device to receive a signal whose frequency is in the extremely high frequency range (i.e., VHF radio wave) with high sensitivity. Preferably, the antenna is operative to receive signals in the frequency range of the Frequency Modulation (FM) band. In other words, the frequency of the signal generally ranges between 87 MHz and 110 MHz. Prior Art Such devices have been disclosed in the prior art, and in particular various extremely different antenna structures have also been proposed. For example, we can refer to U.S. Patent No. 4,754,285, issued toK.S. An antenna. The disclosed solution is characterized by disposing a wire over the entire length of the extendable wristband and continuously wrapping the wire along the width of the wristband. Thus, the length of the wire is greater than the length of the wristband in the rest position and then the wristband is extended. However, this solution does not apply to wristwatches whose wristbands contain two components and whose two components are joined to each other via a fastening device, in addition to occupying a considerable space in the wristband.

The paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) 1260818 A7 Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printed B7___ V. Invention description (2) In response to this particular situation, other solutions have also been proposed, such as passing a simple wire loop through each of the two components of the wristband, and the wire loop is Attached to one end of a wristband component of the watch case to the other end that is configured to snap the component to another component. Also provided at the location of the fastening device is a means for establishing an electrical connection between the two portions of the ring. However, these connecting devices complicate the structure of the wristband and the situation may be more serious because it is preferable to protect the connecting devices from the external environment, especially from the sweat of the user wearing the watch. The impact of this means that considerable protection measures must be taken. SUMMARY OF THE INVENTION The applicant of the present invention has confirmed in his research that the portable electronic device described above can be improved by the present invention, and the improvement is especially due to a simple antenna structure, which is simple in structure. However, it provides a good VHF radio broadcast signal receiving sensitivity. This solution according to the present invention can use such an antenna without requiring much modification to the prior art structure integrated into the present invention. The invention is thus directed to a portable electronic device of the type previously described, characterized in that the antenna comprises at least one of the flat turns made in the form of a spiral winding. Therefore, the space requirement of the antenna in the wristband is extremely limited, while at the same time ensuring that the electronic device according to the present invention has the best reception quality. In the first embodiment, the antenna may be in the shape of a spiral winding (please read the back of the note first and then fill in the page).

Inventions (3) A second flat coil made of the formula. This embodiment can further improve the sensitivity of the device according to the invention, as long as the two coils are connected in series, this embodiment relates only to a very slight increase in the space requirement of the antenna in the wristband. It is conceivable that in order to implement this embodiment in a device comprising a wristband made of two separate parts, one of the two coils is arranged in a first component, The second coil is disposed on the second wristband component. It is also conceivable to deposit each coil, such as a copper path, on a substrate, and in this case, a first coil is placed on a first side of the substrate, The second coil is disposed on the second surface of the substrate. This deformation contributes to the connection of the integrated circuit to the radio broadcast signal receiving circuit, and is particularly advantageous when the integrated circuit is mounted in the casing of the electronic device. Of course, it is preferable to form the substrate for supporting the antenna according to the present invention in a flexible material so that the wrist band can be deformed. In general, since the integrated circuit of the receiving circuit is disposed in the casing of the electronic device, the integrated circuit is connected to the ends of the one or more coils by a metal path. Preferably, the metal paths are supported by an extension of the substrate extending into the interior of the housing. Further, since the coil has a specific spiral shape, an opening is disposed in the substrate to connect the inner end of the coil to the corresponding metal path. In a preferred embodiment, the solution described above is implemented in a timer, in which case the housing includes a timer move order (please read the note on the back and then fill out this page) Order ^1.

Embodiment Fig. 1 is a schematic view of an antenna (1) including a single coil (2) according to a main embodiment of the present invention, and showing a specific shape of a spiral winding coil. Please also note that the coil (2) is disposed on the front face (3) of a substrate (4), and the coil (2) is preferably made of copper and the coil (2) is preferably about several micrometers. Smaller thickness. The substrate (4) has a substantially rectangular shape under the goal of optimizing the surface available in a wristband. Similarly, the spiral winding of the coil (2) has a generally rectangular shape to optimize the available substrate surface. A particularly advantageous system is thus obtained because the surface of the coil (2) can be much larger than a first end (5) of the surface coil (2) in the case where the coil is mounted in the portable device. Located outside the spiral, and extending from a portion (7) of the substrate (4), the rectangular connector (6) extends the first end (5), and the elongated rectangular connection (6) Used to connect the first end (5) of the coil (2) to an integrated circuit (as shown in Figure 2). A second elongated rectangular connector (6) disposed on the extended portion (7) of the substrate and parallel to the first connector (6) is used to connect the first end (9) of the turns (2) Go to the integrated circuit. Since the second end (9) is located within the spiral, an aperture through the substrate (4) is disposed.

A metal path (14) is further provided to complete the electrical connection between the second end (9) of the coil (2) and the second rectangular connector (6). This structure has been described by way of non-limiting example, and anyone skilled in the art will be able to use any other equivalent structure that ensures electrical connection functionality, since the antenna (1) shown in Figure 1 is intended to be mounted in a The portable device is advantageously made of a flexible material to make the substrate (4), especially when a deformable wristband is provided for carrying the electronic device according to the present invention, and more preferably made of a flexible material. Substrate. In this case, a material such as Kapton (registered trademark) or any other material having an equivalent adhesion property to copper and flexibility can be used. Further, the thickness of the substrate (4) is about several tens of micrometers. The manufacture of the antenna (1) relies on techniques well known in the prior art, and in particular in the art of printed circuit fabrication. Those skilled in the art will indeed be able to change to a traditional method in the field without any particular difficulties. For example, we can initially cut a Kapton film to the appropriate size, and the film contains the two openings (1 0) described above and (please read the back of the note before filling this page) Paper scale applicable to China National Standard Rate (CNS) A4 specification (210X 297 mm) -9- 1260818 Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printed A7 B7 V, invention description (6) (12), and a conductive material Fill these two openings. The film is thus prepared to define the substrate (4) of the antenna (1). A layer of copper film is then bonded to each side (3), (11) of the substrate. Partial protection of the two layers of copper film without protecting the pattern that does not correspond to the coil (2), the pattern of the connectors (6) and (8), and the metal path on the back side of the substrate (1 1 ) Part of the pattern of 1 4 ). These unprotected portions are then implemented to obtain a coil (2) such as that shown in Figure 1 and connectors (6), (8). Please note that the antenna (1) shown in Figure 1 depends on the required operating frequency. Those skilled in the art must pay special attention to adjusting the size of the spiral. One of the well-known phenomena in the field of antennas containing coils is indeed the risk of capacitive coupling that may occur in adjacent coil turns. Those skilled in the art will therefore have to pay attention to the distance between the two consecutive coil turns of the spiral, depending on the thickness of the copper used to make the coil and the operating frequency, where capacitive coupling will follow this work. The frequency increases and increases. 2 shows a perspective view of a portable electronic device (15) according to the invention, wherein the portable electronic device (15) is provided with an antenna forming the shape of a wristband component (16) of the wristband. (1 ). Please note that in this figure, the size of the antenna (1) according to the invention advantageously allows the portable device (15) to be mounted in a wristband of a general size. The figure shows the antenna (1) in a curved configuration, which shows the flexible nature of the substrate (4). Please note that an important option is to place the antenna (1) in the vicinity of the upper surface (17) of the wristband component (16). In fact, the human body is usually placed in contact with the human body due to the shielding effect. (Please read the back of the note first and then fill out this page.)

Description of the invention (7) Sensitivity of an antenna in the vicinity, which is the reason why the distance d is likely to reach the maximum flaw. Therefore, the antenna of the electronic device according to the present invention has the highest radio broadcast signal receiving sensitivity. From a practical point of view, the antenna (1) can be integrated into the wristband of the electronic device (15) in a variety of ways. For example, when a wristband component (16) is made of a plastic material, the antenna (1) can be directly overmolded to the wristband component (16), and only the extension of the substrate (4) is exposed. (7). We may also use a wristband component (16) having a recess in the material forming the wristband component, and the recess is substantially larger in size than the antenna (1) so that the antenna (1) can be inserted The recess. We can also use only one wristband component (16) composed of two layers, and when the antenna (1) is disposed between the two layers, the two layers are, for example, sewn together. Of course, the portable electronic device is obviously not limited to the wristband structure, and the wristband structure may include one or two wristband components, and the wristband structure may or may not extend. It is also apparent from the figure that the extension (7) of the substrate (4) carrying the rectangular connectors (6) and (8) extends the inner casing (18) of the portable electronic device (15). To the junction of a printed circuit board (1 9 ). The printed circuit board (1 9 ) contains two openings (20) that pass completely through the printed circuit board (only one opening is shown in Figure 2) and is filled with a conductive material to fill the two openings. Rectangular connectors (6) and (8) are respectively connected to the printed circuit board (1 9 ) on each of the openings (20) to define a coil on the upper surface (21) of the printed circuit board (19) (2) Each (please read the note on the back and then fill out this page) This paper size applies to the Chinese National Standard (CNS) A4 specification (210X 297 mm) -11 - 1260818 A7 B7 Ministry of Economic Affairs Intellectual Property Office staff consumption Cooperative Printing 5, Invention Description (〇) One of the electrical contacts at one end (5) and (9). The connection between the connectors (6) and (8) and the printed circuit board (i9) is accomplished in a conventional manner such as soldering, screws, bonding using a conductive adhesive, or any other equivalent means. The printed circuit board (19) also carries an integrated circuit (22) connected to the integrated circuit (22) by a right dry metal path (23) (only one metal path is shown in Figure 2). Electrical contact (20). The integrated circuit (22) processes the radio broadcast signal received by the antenna (丨) so that the user of the portable electronic device (丨5) according to the present invention can utilize the processed radio broadcast in a form that can be directly utilized. signal. This aspect of the operation of the portable electronic device (15) will not be described in detail herein, since this aspect is only one aspect of the present invention. The structural details relating to the passage of the extension (7) of the substrate (4) carrying the two rectangular connectors (6) and (8) will not be further elaborated. This is because the prior art documents have been proposed. Many solutions. For a reader who is interested, reference is made to the European Patent Application No. 1 03 3 636, issued on Sep. 6, 2000, the disclosure of which is hereby incorporated by reference. In fact, the description of this patent application shows several embodiments of the passage of an electronic connector that passes through a watch case in a waterproof manner. In its entirety, the solution disclosed in the patent application is characterized in that an opening is arranged on the side of the case, and a substantially tubular passage (24) is arranged in the opening. A sealing device (25) is provided between the case (18) and the outside of the tubular passage (24). This channel guides the electrical connectors to the table (please read the notes on the back and fill out this page). This paper size applies to the Chinese National Standard (CNS) A4 specification (210X 297 mm) -12- 1260818 A7 Economy Ministry of Intellectual Property Bureau employee consumption cooperative printing 5, invention description (9) inside the shell, and has a device to ensure that the inside of the channel (24) is sealed from the outside of the case. These seals are formed in the form of a joint (26) such as overmolded near the electrical connectors, and the joint (26) has the same shape as the interior of the passage, thereby ensuring the function of a plug. A device such as an electrical connector that does not itself penetrate the interior of the housing of the electronic device may be provided. We can use a set of bonded contacts as described in the European Patent Application No. 1 86 804, which is even a capacitive coupling obtained in the housing of the device described in European Patent Application No. 1 014 23 1 . From the standpoint of self-sealing, the latter embodiment advantageously facilitates the construction of the outer casing (18) of the device because it does not require the creation of an opening in the outer casing. Figure 3 shows a second embodiment of an antenna (1) of a portable electronic device (15) according to the invention, wherein the antenna (1) comprises two coils printed on the same substrate (28) (2) ), (27). The type of the substrate (28) is the same as that of the substrate (4) described above with reference to Fig. 1, but the only difference is that the thickness of the substrate must be substantially larger than the thickness of the substrate (4) shown in Fig. 1. In fact, since the coils (2), (27) are disposed on each side (29), (30) of the substrate (28) so that the two turns are in a relative manner, the coils may thus have one Staggered capacitive coupling that is detrimental to the reception quality of the antenna (1). As mentioned earlier, the degree of capacitance coupling depends on the width of the individual windings of coils (2), (27), and the operating frequency. Those skilled in the art are adjusting the thickness of the substrate (28) in order to find out the space requirement of the antenna (1) and capacitive coupling to the antenna (1) to receive (please read the back of the note first and then fill in this page).

Invention Description (ih A compromise between the effects of sensitivity. As can be seen from Figure 3 Each element that has been described with reference to Figure 1 'i.e., the coil (2) has a first end (5) outside the helix and a second end (9) ' within the helix and is provided Electrical connections and metal paths can be established on the back side (30) of the substrate (28) by two openings (10), (12)' in the rectangular connectors (6), (8) and the substrate (28). The second coil (27) also has a substantially spiral shape, and the second coil (27) is printed on the back surface (30) of the substrate (28). The second coil outside the spiral The first end (31) of (27) is a metal path (14) connected to the back side The second end (32) of the second coil (27) located within the spiral is connected to the opening (10), and the opening (10) is the second end of the first coil (2) ( 9) is connected to the back surface (30) of the substrate (28), so that the two coils (2) and (27) are connected in series. In addition, please note that the sensitivity of the antenna (1) obtained for improvement is also along The opposite directions wind the two coils (2), (27). In fact, in the non-limiting example shown in Figure 3, the upper (2 9 ) of the substrate (2 8 ) is negative. The angular direction (negativetrig ο η 〇me 11· ic direction ) (ie, when we are from the first outer end (5 ) of the coil ( 2 ) toward the inner end ( 9 ) of the coil ( 2 ) along the coil ( 2) when moving) winding the coil (2); and in the direction of the positive trigonometry (ie, when we are from the first outer end (3 1 ) of the coil (27) towards the inner end of the coil (27) (32 ) while moving along the coil (27)) the winding is located (please read the back of the note first and then fill out this page).

Invention Description (l) l Second coil on the back (30) of the substrate (28) (27) In this manner, the respective induced currents generated by applying an identical magnetic field to the respective wires 2(2), (27) have the same flow direction, and thus the induced current phases are first Plus, and then received by the radio broadcast signal processing integrated circuit (22). Also note that since the coils (2) and (27) are not stacked in the configuration shown in Figure 3, the risk of capacitive coupling is reduced when compared to a configuration in which the windings are stacked. The method of manufacturing the antenna (1) shown in Fig. 3 is similar to the method of manufacturing the antenna shown in Fig. 1. Similarly, the configuration of the antenna has the same requirements as the configuration of the antenna shown in Fig. 2 above. The foregoing description corresponds to the preferred embodiment of the present invention, and the description is not to be construed as limiting the invention. In particular, when the antenna includes several turns, the description should not be regarded as the number of turns and between the coils. The relative configuration is limited. In fact, we can use, for example, one of two coils having two coils supported by two different substrates, and the substrates are respectively mounted on two separate faces of the outer casing of the portable electronic device according to the present invention. In other words, in the case of a wristband having two wristband components, each of the two turns can be mounted in a different wristband component. In this case, of course, some additional contacts and some additional metal paths must be placed on the printed circuit board. A watch mechanical moving unit (code 33 in FIG. 2) coupled to the time display device can also be integrated into the portable electronic device according to the present invention (read the reading on the back side and then fill in the page).
