Abstract:
1. Antenna device comprising: a first electromagnetic waves radiating slot antenna and a second electromagnetic waves radiating slot antenna, said first and second slot antenna being symmetric with respect to a point; and a connection means for connecting said first and second slot antennas to means for exploiting electromagnetic waves, the connection means consisting of a first supply line electromagnetically coupled to the first slot antenna and a second supply line electromagnetically coupled to the second slot antenna, the first and the second supply lines being connected on one side to a common supply line extending in a plane passing through the point of symmetry and on the other side to an electronic component enabling a short circuit or an open circuit to be simulated at the end of the first supply line and an open circuit or a short circuit to be simulated at the end of the second supply line, wherein the first and second slot antennas are fitted with means enabling a circularly polarized wave to be radiated.
