Abstract

An integrated antenna system for telecommunications comprises at least one substantially flat and circular antenna provided with a rotation axis coinciding with its axis, the antenna being fixedly joined to a support itself comprising a rotation axis. The rotation axis of the antenna is inclined by an angle θ relative to the rotation axis of the antenna support and the antenna beam forms an angle φ relative to the rotation axis of the antenna.

Claims

1. An integrated antenna system for telecommunications, comprising:

a substantially flat and circular antenna having a rotation axis coinciding with its axis;

a support having the antenna fixedly joined thereto, wherein said support has a rotation axis, at least two flat, substantially circular antennas having a diameter D₁, D₂, each of the antennas being inclined by an angle α

relative to the antenna support, wherein the antenna has a beam inclined by an angle φ

₁ and the antenna has a beam inclined by an angle φ

₂ relative to the axis of rotation of the antenna; and

a device adapted to making the antennas and their support rotate.

2. An antenna system according to claim 1 wherein the α

₁=α

₂=20 degrees, φ

₁=60° and

φ

₂=20°

.

3. An antenna system according to claim 1, wherein the diameter of the antenna is chosen as a function of the communications application.

4. An antenna system according to claim 1, comprising a radome containing the antenna elements.

5. An antenna system according to claim 1, positioned on an aircraft fuselage.

6. An antenna system according to claim 2 comprising a radome containing the antenna elements.

7. A method for sending out one of more antenna beams in a telecommunications system, wherein an assembly comprising at least two substantially circular, flat antennas with a diameter D₁, D₂ is made to rotate, each of the antennas is inclined, for example, by an angle α

relative to the antenna support, the antenna presenting a beam inclined by an angle φ

₁ and the antenna has a beam inclined by an angle φ

₂ relative to the rotation axis of the antenna, the rotation being done in relative bearing about a main axis vertical to the support on which the assembly is positioned.
