Description
Alle bisherigen Lösungen von Funkarmbanduhren können wie folgt klassifiziert werden:All previous radio-controlled watch solutions can be classified as follows:
a) Funkarmbanduhren mit einer Langwellenantenne außerhalb des Uhrengehäuses a) Radio-controlled wristwatches with a long-wave antenna outside the watch case
b) Funkarmbanduhren mit einer Langwellenantenne am Uhrengehäuse oder derart, daß Teile des Gehäuses oder das gesamte Gehäuse aus ferromagnetischem Material bestehen und als Antennenelement genutzt werden.b) Radio-controlled wristwatches with a long-wave antenna on the watch case or in such a way that parts of the case or the entire case are made of ferromagnetic material and are used as an antenna element.
c) Funkarmbanduhren, in denen uhrentechnische Baugruppen, z.B. die Platine aus ferromagnetischem Material bestehen und als Antennenelement genutzt werden.c) Radio-controlled wristwatches in which watch components, e.g. the circuit board, are made of ferromagnetic material and are used as an antenna element.
Mit diesen Lösungen soll ein möglichst großer Antennengewinn durch maximales Volumen von ferromagnetischem Material in der Antennenanordnung erzielt werden, bzw. groß bauende Antennen außerhalb des Uhrengehäuses möglich sein.These solutions are intended to achieve the greatest possible antenna gain through the maximum volume of ferromagnetic material in the antenna arrangement, or to make large antennas possible outside the watch case.
Die Schriften G 89 01 512.6, DE 39 41 913 und DE 35 08 366 dokumentieren hierzu den technischen Stand.The documents G 89 01 512.6, DE 39 41 913 and DE 35 08 366 document the technical status in this regard.
Nachteilig sind die komplizierten und damit kostenungünstigen ferromagnetischen Teile und eine im magnetischen Sinn nicht optimale Geometrie hinsichtlich des Längen-Durchmesserverhältnisses für Ferritantennen. In der DE 3508366 und G 8815 967.1 ist die Antenne im Uhrenarmband eingearbeitet, was Nachteile für die guten Trageeigenschaften und der Wasserdichtheit verursacht. Lösungen mit gekoppelten Antennen, wie in DE 35 46 471 und G 84 32 848.8 beschrieben, sind für Armbanduhren wegen Ihres großen Volumenbedarfs nicht geeignet.The disadvantages are the complicated and therefore cost-effective ferromagnetic parts and a geometry that is not optimal in the magnetic sense with regard to the length-diameter ratio for ferrite antennas. In DE 3508366 and G 8815 967.1 the antenna is incorporated into the watch strap, which causes disadvantages for the good wearing properties and water resistance. Solutions with coupled antennas, as described in DE 35 46 471 and G 84 32 848.8, are not suitable for wristwatches due to their large volume requirements.
Optimale Ergebnisse hinsichtlich eines hohen Antennengewinns, guter Richtcharakteristik und geringer Störanfälligkeit erzielt man mit geraden, stabförmigen Ferritantennen aus reinem Sintermaterial ohne weitere Zusätze, z.B. wie Kunststoffbindungen, bei einem Längen-Durchmesserverhältnis von ca. 5 zu 1.Optimum results in terms of high antenna gain, good directional characteristics and low susceptibility to interference are achieved with straight, rod-shaped ferrite antennas made of pure sintered material without any further additives, e.g. plastic bonds, with a length-diameter ratio of approx. 5 to 1.

Die anspruchsgemäße Erfindung ewjioglj-cht fleffiSinfcau einer solchen Antenne direkt in ein Armbanduhrgehäuse.The invention according to the claim incorporates such an antenna directly into a wristwatch case.
In Fig. 1 ist ein Uhrengehäuse entsprechend der Ansprüche dargestellt. Im Inneren des Gehäuses 1, welches z.B. aus Kunststoff besteht, sind die Baugruppen Elektronikmodul 2 mit Controller 3 und Empfänger 4, Uhrwerk 5, Langwellenantenne 6 und Batterie 7 angeordnet. Das Uhrenzifferblatt 8 überdeckt die Antenne 6 teilweise.In Fig. 1, a watch case according to the claims is shown. Inside the case 1, which is made of plastic, for example, the electronic module 2 with controller 3 and receiver 4, clockwork 5, long-wave antenna 6 and battery 7 are arranged. The watch face 8 partially covers the antenna 6.
Die Fig. 2 ist im Maßstab 1 zu 1 gezeichnet und zeigt, daß trotz der konventionellen Antennengestaltung eine gute Unterbringung im Uhrgehäuse bei üblicher Gehäusegröße möglich ist. Besonders günstig ist die anspruchsgemäße Anordnung in Verbindung mit einem Langwellenempfänger hoher Eingangsempfindlichkeit. Die Messungen haben gezeigt, daß mit den verfügbaren Empfängerschaltkreisen und der Antenne 6 höhere Empfindlichkeiten im Vergleich zu bekannten Lösungen erreicht werden.Fig. 2 is drawn on a scale of 1:1 and shows that despite the conventional antenna design, it is possible to accommodate it well in the watch case with a normal case size. The arrangement according to the claim is particularly advantageous in conjunction with a long-wave receiver with high input sensitivity. The measurements have shown that with the available receiver circuits and the antenna 6, higher sensitivities can be achieved compared to known solutions.
