Abstract
A device, applicable to the field of wireless transmission, receives and/or transmits electromagnetic waves with radiation diversity. This device comprises, on a common substrate (3), at least one antenna of the slot type (1) formed by a closed curve, known as a slot antenna, electromagnetically coupled to a first supply line (6), and an antenna radiating parallel to the substrate (2), positioned inside the slot antenna and connected to a second supply line. The first and second supply lines are connected via a switching means to means to exploit the electromagnetic waves.
