US 6600901 B1Abstract
The mobile phone (1) has an antenna arrangement (5) for radiating different radiation patterns (30, 35, 40) according to an actual operation mode of the mobile phone (1). The different radiation patterns include two radiation patterns that avoid introducing radiation into the head of a user during an active telecommunications connection. At least two operation modes of the mobile phone (1) are assigned to a different radiation patern respectively. During an active operation mode, the assigned radition pattern is selected and activated. A change between the operation mode causes switching between the assigned radiation patterns. In a preferred embodiment the radiation pattern is omindirectional (30) during an idle mode, is directional (35) during active telecomunications connections and is approximately omindirectional with a preferential direction (40) during other active telecommunications connections in which control signal are exchanged.
The present invention relates to a mobile phone. A mobile phone including an antenna arrangement with an antenna element, which is able to radiate in two different radiation patterns, has already been described in German Patent application DE 197 23 331.
The invention proceeds from a mobile phone in accordance is with the generic class of the independent patent claim.
It is an object of the present invention to provide an improved mobile phone of the above-described type having a plurality of operation modes, especially a mobile phone which avoids introducing radiation into the head of a user during an active telecommunications connection.
Examples of the invention are shown in the figures and explained in greater detail in the description below.
In FIG. 1 designates 1 a mobile phone comprising a baseband part 20 and a radio frequency part 25. The baseband part 20 is connected to the radio frequency part 25. The radio frequency part 25 is connectable via a first switch 45 to a first antenna element 10 providing a first radiation pattern 30 which is an omnidirectional radiation pattern. The radio frequency part 25 is connectable to a second antenna element 15 via a second switch 50, the second antenna element 15 providing a second radiation pattern 35 which is a directional radiation pattern. The radio frequency part 25, the first switch 45 and the second switch 50 are arranged in a first radio frequency module 70. The first switch 45 is controlled via a first control line 80 by the baseband part 20. The second switch 50 is controlled via a second control line 85 by the baseband part 20. The first antenna element 10 and the second antenna element 15 constitute an antenna arrangement 5.
