"Handy mit gerichteter Sendeantenne""Mobile phone with directional transmitting antenna"
Die Erfindung betrifft eine Sende- und Empfangsantenne für Mobilfunktelefone. Die Antenne soll derart modifiziert sein, daß die in Richtung Kopf emittierte Leistung der elektromagnetischen Welle, die sich im Mikrowellenbereich befindet, um 10- 2OdB vermindert wird und daß damit die Grenzwerte für die Emission elektromagnetischer Strahlung für elektrische Geräte, die in diesem Bereich bei 10- 25 mWatt liegen, eingehalten werden.The invention relates to a transmitting and receiving antenna for mobile telephones. The antenna is to be modified in such a way that the power of the electromagnetic wave emitted in the direction of the head, which is in the microwave range, is reduced by 10-20 dB and that the limit values for the emission of electromagnetic radiation for electrical devices, which are 10-25 mWatt in this range, are thus complied with.
Dadurch wird der Diskussion um mögliche Auswirkungen der entsandten Mikrowelle der Handys Rechnung getragen. Werden die Grenzwerte eingehalten, werden keine Auswirkungen mehr erwartet, da sich die Dimensionierung der Leistungsgrenzwerte an den Nervenströmen des menschlichen Körpers orientiert.This takes into account the discussion about possible effects of microwaves emitted by cell phones. If the limits are complied with, no further effects are expected, as the dimensioning of the power limits is based on the nerve currents of the human body.
Hochfrequente elektromagnetische Wellen sind üi diesem Frequenzbereich durch Blenden nur sehr bedingt abschirmbar, da eine leitende Blende in der Regel resoniert.High-frequency electromagnetic waves can only be shielded to a very limited extent by apertures in this frequency range, since a conductive aperture usually resonates.
Daher wird vorgeschlagen, die Welle zum größten Teil zu absorbieren. Das geschieht dadurch, daß Ladungsträger, in erster Linie Elektronen, in der Antennenrichtung gedampfte Resonanzschwingungen absolvieren. Die Dämpfung erreicht man in Leitern etwa durch ohmsche Widerstände oder dadurch, daß man das Material von der eigentlichen Sendeantenne isoliert und als Empfangsantenne schaltet, die die entsandte Energie wieder dem Akku zufuhrt. Nutet man Metalle, so führen nichtferromagnetische Materialien nicht zu Streuverlusten der emittierten Wellle.It is therefore suggested that the wave should be absorbed for the most part. This is done by charge carriers, primarily electrons, undergoing damped resonance oscillations in the direction of the antenna. Damping is achieved in conductors by using ohmic resistances or by isolating the material from the actual transmitting antenna and switching it to a receiving antenna, which feeds the transmitted energy back into the battery. If metals are used, non-ferromagnetic materials do not lead to scattering losses of the emitted wave.
Eine andere Ausgestaltung der Erfindung nutzt darüberhinaus die Polarisation der emittierten elektromagnetischen Welle in der Ebene, die durch die Antennenrichtung und die Ausbreitungsrichtung bestimmt ist: In Polarisationsfiltern befinden sich lineare Leitungsbänder, in denen bei Ausrichtung in Antennenrichtung Ladungsträger die einfallende polarisierte Welle nahezu vollständig absorbieren.Another embodiment of the invention also uses the polarization of the emitted electromagnetic wave in the plane determined by the antenna direction and the propagation direction: Polarization filters contain linear conduction bands in which charge carriers almost completely absorb the incident polarized wave when aligned in the antenna direction.
Andere Polarisatoren, wie etwa Feldspat- Kristalle (Nicol'sches Prisma) nutzen Resonanzeffekte von Atomen, um die Welle total zu reflektieren.Other polarizers, such as feldspar crystals (Nicol prism) use resonance effects of atoms to totally reflect the wave.

In Figur 1 sehen wir den Antennendipol (1), sowie eines der oben beschriebenen Materialien (2), das hierbei von (1) durch eine Isolationsschicht (3) getrennt sein kann.In Figure 1 we see the antenna dipole (1) as well as one of the materials described above (2), which can be separated from (1) by an insulation layer (3).
In Figur 2 erkennen wir den Antennendipol (1), sowie eines der Materialien (2), das hier sphärisch an der Antenne in Richtung zum Kopf des Handy- Benutzers angebracht ist. Hier ist (2) in Form einer Folie dargestellt. Für den Fall einer Polarisationsfolie nach Schutzanspruch 7 ist eine derartige Anordnung angebracht. Dabei ist die Polarisationsrichtung die Antennenrichtung.In Figure 2 we can see the antenna dipole (1) and one of the materials (2), which is attached spherically to the antenna in the direction of the mobile phone user's head. Here (2) is shown in the form of a film. In the case of a polarization film according to claim 7, such an arrangement is appropriate. The polarization direction is the antenna direction.
ta Figur 3 erkennen wir die Aufsicht auf den Antennendipol (1), welcher von dem Absorptionsmaterial (2), welches in diesem Fall elektrisch leitend ist, durch einen Isolator (3) getrennt ist und darüber hinaus über eine ohmsche Impedanz R mit (1) verbunden ist.In Figure 3 we can see the top view of the antenna dipole (1), which is separated from the absorption material (2), which in this case is electrically conductive, by an insulator (3) and is also connected to (1) via an ohmic impedance R.
