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.
Claims8
An integrated antenna system for telecommunications comprising:
- at least two flat, substantially circular rotatable antennas fixedly joined to a single rotatable antenna support having a rotation axis central to the at least two antennas, each antenna being provided with a rotation axis coinciding with its axis, the at least two antennas having a diameter D1, D2, respectively;
- wherein each antenna is inclined at an angle α relative to the antenna support;
- wherein each antenna has a beam inclined at an angle relative to its axis of rotation, such that the multiple antennas cover complementary and different elevation fields and;
- wherein the antenna system comprises a device adapted to making the antennas and their support rotate.
A method for sending out multiple antenna beams in a telecommunications system comprising an antenna assembly that includes at least two substantially circular, flat antennas with a diameter D1, D2, mounted thereon, the antenna assembly having a main vertical axis central to the at least two antennas, wherein each antenna is inclined by a first angle relative to an antenna support, the method comprising:
- transmitting a first antenna beam inclined by a second angle relative to a rotation axis of the first antenna;
- transmitting at least another antenna beam inclined by another angle relative to the rotation axis of the at least other antenna;
- rotating each antenna about its axis;
- and
- rotating the antenna assembly about the main vertical axis, such that the multiple antennas cover complementary and different elevation fields.
