1. A wireless communication device comprising at least three elementary antennas each comprising:
at least two loops, two adjacent loops being configured to be traveled by currents having opposite circulation directions, each loop of each antenna delimiting an inner surface called loop surface, in which the elementary antennas are offset two by two in a rectilinear direction and wherein, for each loop of each antenna, a part of the surface of this loop is superimposed with a portion of a loop surface of each other elementary antenna, the part of said loop surface having an area smaller than the area of the loop surface of said loop, each loop of each antenna being partitioned into loop partitions having a surface, each loop partition being delimited by at least one loop part of a loop of another antenna, each surface of a loop partition having an area of less than or equal to one third of the area of the surface of this loop,
wherein the elementary antennas extend in a same plane and are configured to emit an electromagnetic field in a three-dimensional zone of the space, the electromagnetic field emitted in the three-dimensional zone being continuous along a direction parallel to the rectilinear direction.
