Patent ID: 8593361

Claim:
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: a first set of antennas, with: a first antenna, a second antenna, a third antenna, arranged on the plane substrate in the opposite manner to the first antenna, a fourth antenna, arranged on the plane substrate in the opposite manner to the second antenna, said antennas each presenting a bisector, wherein the bisector of opposing first and third, and second and forth, antennas are distant from and parallel to one another, and the bisectors of any two consecutively arranged antennas are perpendicular with respect to each other; each of said antennas being tapering slot antennas, a tapering originating at a vertex and presenting a left profile and a right profile, wherein the left profile and the right profile of each antenna is dissymmetric with respect to the bisector of that same antenna and which bisector passes through the respective vertex, the radiating device comprising a switching circuit capable of activating one or more of the antennas.
