It can further be provided that the light guide of the shape of the antenna is adjusted, for example, extends over its entire length or having loops or turns. In addition, it can be provided that the light guide retraces certain forms, which have a certain signal effect. For example, may be wound in the form of symbolized phone, a light guide to display an illuminated by an incoming call telephone icon. However, it can be wound in the form of a watch to remind by a visual symbol of an appointment.

According to a preferred embodiment may be superiors continue to see that the antenna comprises a plurality of illuminable light conductor, the light from a light source is coupled into a respective light guide. Thus, various light guides can be activated depending on the function performed, and thereby display various events.

It can further be provided that the light source illuminates when an incoming call. This has the advantage that the user recognizes whether an incoming call without an audible signal must be issued, which in certain situations, such as theater, would be disruptive.

It can further be provided that the intensity of the light source is adjustable, whereby it is possible to output different comparison signals by the magnitude of the luminosity. Furthermore, intensity patterns can be used the light source to output certain signals further, for example, a rise and fall of the intensity of the light source or alternately strong and weak fluorescent signal.

Furthermore, it can be provided according to a preferred embodiment that the light source by a user directly, for example via a keyboard, switched on and off. This has the advantage that the transmitting / receiving device can be used with the antenna as a flashlight.

There may further be provided that the light source is controlled by a time control. This is advantageous because it can realize a clock function and an appointment reminder function in the transmitting / receiving device by indicating a desired date by an optical signal. Accordingly, it may be provided that the optical signal is designed so that it is possible to assign a specific date at its output, ie for example can determine in color, intensity, variation of the intensity, etc., and thus the nature of the particular event.

In a further preferred embodiment that the light source is activated on receipt of a specific information can be provided. This has the advantage that the user of the transmitting / receiving device is drawn regardless of an acoustic signal by a light signal of the antenna to the input of a particular information advantage. Such information can be, for example a text message, a fax or something similar. Further features and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings. They show:

Fig. 1 is a sectional view of a transmitter / receiver unit with illuminable antenna, Fig. 2 shows another embodiment of the invention

Antenna with spiral-shaped lightguide Fig. 3 shows a further embodiment of the antenna according to the invention with two light guides, and

Fig. 4 shows another embodiment of the inventive antenna with spiral symbols to optical fibers.

Fig. 1 shows a mobile telephone 1 having an illuminable arrival antenna 2 and a housing 10 in which a printed circuit board 3 is located. On this circuit board contains electronic circuitry (not shown) to perform the function of the mobile telephone 1 and a light source 4. The light source 4 couples light into an optical fiber 5, a, which protrudes with its presence the end in the antenna. 2 The antenna 2 has a transparent sheath 6 through which the light emerging from the optical waveguide 5 Light is output into the environment. In the antenna into a further sufficient RF antenna element 7 which is connected to the circuit on the circuit board 3 in compound and transmits the radio signals and receives.

The light source 4 is preferably configured as a light emitting diode or laser diode which absorbs much less energy than, for example light bulbs. Moreover, light-emitting diodes / LD directional light emission characteristics, which is suitable for coupling into an optical fiber. At the side facing away from the light source 4 the end of the optical fiber 5, the optical fiber 5 in the region which projects into the antenna 2 is roughened (shown in dotted lines), so that light emerges over the entire roughened length. In this way it is achieved that the antenna 2 has the most uniform possible lighting effect. This is supported by the sleeve is configured diffuse 6, so that the light emitted from the light guide 5 is scattered in the casing, so that the position of the optical fiber 5 is no longer recognizable outside of the antenna. 2

The light source 4 is connected to the circuits on the circuit board 3. Thus, the light source according to the functions provided by the circuit can be controlled and is therefore independent of the transmission and reception of radio signals. It lights such as when receiving a call. In addition, any other functions of the mobile phone 1 with a light signal at the antenna 2 can be coupled. For example, can be an event reminder indicated by a particular flare. In addition, the mobile telephone 1 may also be used as a flashlight, where preferably the light source 4 outputs their maximum possible power to the light guide. 5 The torch function is then activated by eg a button or a defined key combination on a keypad of the mobile device.

Moreover, the various functions can be indicated by different light signals of the light source. 4 For example, the light source 4 show an incoming call by simply steady on or blinking, but it can change the light intensity flowing, so that a pulsating light signal. The light source 4 may further include a plurality of light-emitting diodes with different colors, which are mutually separately controllable so that different colors or color combinations via the optical fiber 5 can be output. Thus, the range of options for outputting different signals according to different functions of the mobile phone 1 is increased. Thus, the Receiving a call can for example be indicated by the flashing of the antenna in different colors, wherein successively a certain color sequence is output. Such color sequences can also be used to allow the user identifies the called function of the mobile terminal 1 on the basis of the output light signal. Of course, other functional can be displayed by such a color sequence ons such as arrival of a message, appointment reminder, among others.

Fig. 2 shows another embodiment of an illuminated antenna 2, wherein the shading effect of the RF antenna element 7, which can not be made transparent in most cases, is avoided. Here, the RF antenna element 7 is spirally surrounded by a light guide 5 that is roughened diffuse in the antenna 2 in the region of the RF antenna element 7 so that it emits light over its entire length te. Since the RF antenna element 7 in the

is center of the spiral shaped light guide, no shading occurs, so that the external observer, especially when the envelope of the antenna is configured diffuse, the RF antenna element 7 can not perceive.

Fig. 3 shows an illuminable antenna 2 in the two light guide 5 are provided. The light conductors can be supplied with two different colored light sources in the housing of the mobile phone with light. This gives a higher

Luminosity of the antenna and different signal effects by using different colors and color mixtures in the antenna.

In this way, as well as already described in Figure 2, the shading of light from the light guide through the RF antenna element are avoided 7, by arranging the two optical waveguides and the RF antenna element, so that they extend parallel to and facing each other , It goes without saying that instead, more than two light guides and multiple light sources may be provided.

To display various functions in accordance of a further embodiment which is shown in Figure 4, two

out light guide from the mobile phone to the antenna. Each of the light guide is wound in a predetermined shape and roughened at certain locations, so that symbols 8, 9 are formed, the shape of the user stuffs a vermit- information. Such a light guide can be in the form of a Briefku- verts 8 5, for example, indicating to the user by an optical symbol, that an SMS message has been received. Here, the optical fiber 5 is roughened on the outside only in the region of the symbol, so that only the symbol 8, 9 can be seen from the outside. The envelope should be less light scattering in this case, so that the symbol can be clearly seen. It may in this respect provided that the symbol is illuminated permanently or displays only at certain time intervals to the user that a short message has been received. One of further light guides 5 can be designed in the form of symbolized telephone set 9, indicating to the user that an incoming call, an incoming call was not accepted, oa The features disclosed in the foregoing description, in the claims and in the drawings features the invention can be essential to implementing the invention in its various embodiments both individually and in any combination.
