The present invention relates to a multi-sector radiating device intended to receive and/or transmit electromagnetic signals, comprising at least, arranged on a plane substrate: a first set of antennas, with: a first antenna, a second antenna, a third antenna, arranged in the opposite manner to the first antenna, a fourth antenna, arranged in the opposite manner to the second antenna, the antennas being longitudinal radiation slot type antennas, said antennas each presenting a bisector, wherein the radiating device comprises a switching circuit capable of activating one or more of the antennas, and notably all the antennas of the first set of antennas, —and in that the bisectors of the opposed antennas on the substrate are not combined.
1- Planar multi-sector radiating device intended to receive and/or transmit electromagnetic signals, comprising at least, arranged on a plane substrate covered by a conductive material:
2- Radiating device according to claim 1, wherein the left profile of one of the antennas of the first set of antennas presents one extremity forming a right angle with the right profile of the antenna consecutive to the considered antenna,
3- Radiating device according to claim 1, wherein the switching circuit is at the level of a central part of the antenna network, the switching circuit being linked to the slot of each of the antennas by means of a connection line.
4- Radiating device according to claim 1, each antenna of the antenna network presenting the following characteristics:
5- Radiating device according to claim 4, wherein each antenna presents the following dimensioning:
6- Radiating device according to claim 1, comprising a second set of longitudinal radiation antennas of tapered slot antenna type, the second set of antennas comprising additional antennas, the slot of each of the additional antennas being set at profile level with a greater dimension than one of the antennas of the first set of antennas.
7- Radiating device according claim 6, wherein the operating frequency of the second set of antennas is different from the operating frequency of the first set of antennas.
