| 摘要 |
The invention concerns a telecommunication device with electronic scanning arrays shaped along a first surface with symmetry of revolution, comprising: a first array of first radiating sources (5) arranged along said surface to operate about a first centre frequency. The invention is characterised in that the device further comprises: a second array of radiating sources arranged along a second surface with symmetry of revolution to operate about a second centre frequency, the first and second sources being respectively arranged such that a first source, respectively a second source, is not opposite a second source, respectively a first source, along a cross cut of the first and second surfaces pointing on the first source, respectively the second source. The invention also concerns a telecommunication terminal in a constellation system by satellites and a wireless communication terminal for communicating with household equipment comprising said inventive device.
