Abstract

The high frequency, multiple beam antenna system comprises a focusing device having a profile of revolution created by the cross section of a dielectric lens rotating about an axis located in its plane and radiating elements with form of directional-printed antennas with longitudinal radiation.

Claims

1. High frequency, multiple beam antenna system, comprising a focusing device having a profile of revolution created by the cross section of a dielectric lens rotating about an axis located in its plane, wherein it comprises radiating elements in the form of directional printed antennas with longitudinal radiation.

2. Antenna system according to claim 1, in which the radiating elements are printed on a common substrate.

3. Antenna system according to claim 1, in which each radiating element is a “

Vivaldi”

type printed slot antenna.

4. Antenna system according to claim 2, further comprising transmit and/or receive and/or switching circuits arranged on said common substrate.

5. Antenna system according to claim 4, in which the focusing device has an annular profile of revolution, in which the substrate is disc-shaped and in which the radiating elements are arranged along the periphery of the substrate.

6. Antenna system according to claim 5, in which the radiating elements are arranged around transmit and/or receive and/or switching circuits.

7. Antenna system according to claim 1, in which the focusing device is made of synthetic foam and has a circular radial section.

8. Antenna system according to claim 1, in which the focusing device is made of synthetic foam and has a crescent-shaped radial section.

9. Sending/receiving station for a mesh-network-architecture wireless communication network, including an antenna system comprising a focusing device having a profile of revolution created by the cross section of a dielectric lens rotating about an axis located in its plane, wherein it comprises radiating elements in the form of directional printed antennas with longitudinal radiation.

10. Mesh-network-architecture wireless communication network, wherein it comprises at least one or more sending/receiving stations according to claim 9.
