Description
Ausgehend vom Ziel der Erfindung besteht die Aufgabe darin, die elektromagnetische Feldstärke am Körper der telefonierenden Person auf ein Minimum zu beschränken. Erf indungsge:- mäß wird die Aufgabe dadurch gelöst, daß das Mobiltelefon mit einem Antennensystem ausgestattet wird, welches sich selbsttätig auf die Basisstation oder aber auf Sender und Empfänger an verschiedenen Standorten ausrichtet. Das Ausrichten erfolgt dabei allein auf elektronischem Weg, ohne mechanisch bewegte Teile. Erreicht wird dieses durch Einsatz einer, aus vielen kleinen Einzelelementen bestehenden Anordnung, bei der jedes Element mit anderen zusammenschaltbar ist und auch einzeln als Abnehmer oder gespeistes Element betrieben werden kann. Durch entsprechendes Zusammenschalten der Elemente und Wahl der Abnahmepunkte läßt sich eine gewünschte Richtcharakteristik erreichen,, ohne das die Antenne mechanisch ihre Position verändern muß. Die Richtcharakteristik läßt sich bei einer entsprechenden Feldanordnung der Elemente in weiten Grenzen verändern. Um die Abmessungen einer solchen Antenne klein zu halten, wäre es denkbar, einige Elemente auch im Empfangsmodus gezielt phasenverlagert mit der zu erwartenden Empfangsenegie vom Sender zu speisen, um damit einen virtuell vergrößerten Resonator zu schaffen, der größer als die Antennenabmessungen selbst sein kann.Based on the aim of the invention, the task is to limit the electromagnetic field strength on the body of the person making the call to a minimum. According to the invention, the task is solved by equipping the mobile phone with an antenna system which automatically aligns itself to the base station or to the transmitter and receiver at different locations. The alignment takes place purely electronically, without mechanically moving parts. This is achieved by using an arrangement consisting of many small individual elements, in which each element can be connected to others and can also be operated individually as a receiver or fed element. By connecting the elements together accordingly and choosing the pickup points, a desired directional characteristic can be achieved without the antenna having to mechanically change its position. The directional characteristic can be changed within wide limits with an appropriate field arrangement of the elements. In order to keep the dimensions of such an antenna small, it would be conceivable to feed some elements in the receive mode with the expected receive energy from the transmitter in a phase-shifted manner in order to create a virtually enlarged resonator that can be larger than the antenna dimensions themselves.
Die Kontrolle über die Antennenzusammenschaltung wird über ein Computersystem erreicht, welches die Zusammenschaltung für die gewünschte Charakteristik festlegt und Einspeisungs- und Abnahmepunkte bestimmt. Damit läßt sich die Antenne des Mobiltelefons automatisch auf maximale Empfangsfeldstärke ausrichten. Wenn die Position von ortsfestem Sender und Empfänger gleich ist, kann das Mobiltelefon direkt in Richtung des Senders zurücksenden und benötigt so wesentlich weniger (mindestens Faktor 10) Energie, als wenn es ungerichtet senden würde. Außerdem kann in der Richtcharakteristik der Kopf des Teilnehmers mit berücksichtigt werden, wenn er günstig zur ortsfesten Station steht. Wenn mehrere ortsfeste Stationen zur Auswahl stehen, kann über ein entsprechendes Protokoll die für die Strahlenbelastung des Teilnehmers günstigste Station ausgewählt werden, in die sich das Mobiltelefon automatisch einbucht. The control of the antenna interconnection is achieved via a computer system, which sets the interconnection for the desired characteristics and determines the feed and take-off points. This allows the mobile phone's antenna to be automatically aligned to the maximum reception field strength. If the position of the fixed transmitter and receiver are the same, the mobile phone can send directly back in the direction of the transmitter and thus requires significantly less energy (at least a factor of 10) than if it were to send in an undirected manner. In addition, the subscriber's head can be taken into account in the directional characteristics if it is in a favorable position relative to the fixed station. If there are several fixed stations to choose from, the station that is most favorable for the subscriber's radiation exposure can be selected using an appropriate protocol, and the mobile phone will automatically log into it.
Ein weiterer Aspekt ist die Strahlenbelastung durch Reflektionen an sich in der Nähe befindenden Metallteilen. Sie können durch entsprechende Pulse und Messung von Richtung und Laufzeit bestimmt werden. Wenn die Möglichkeit besteht,,Another aspect is the radiation exposure caused by reflections from nearby metal parts. This can be determined by appropriate pulses and measuring the direction and travel time. If possible,

können sie durch Veränderung der Abstrahlcharakteristik der MobiIfunkantenne ausgeblendet werden.They can be blocked out by changing the radiation characteristics of the mobile antenna.
Sind der Standort von festem Sender und Empfänger nicht
gleich, muß ein entsprechendes Protokoll (ähnlich GPS) benutzt
werden, damit das Funktelefon seine relative Position zu den ortsfesten Stationen ermitteln kann, um daraufhin
seine Sendecharakteristik auf den ortsfesten Empfänger einzustellen. If the location of the fixed transmitter and receiver are not
the same, an appropriate protocol (similar to GPS) must be used
so that the radio telephone can determine its relative position to the fixed stations and then
to adjust its transmission characteristics to the stationary receiver.
