Abstract: Radiofrequency system includes a main antenna and a radiation pattern adaptation device including a printed circuit, on which two radiating strands and a reflector are printed, and on which a switching circuit is mounted, connected to the two radiating strands and arranged to be controlled, such that when the switching circuit is in a blocked mode, the radiofrequency system has a first radiation pattern; and when the switching circuit is in a passing mode, the two radiating strands form a halfwave dipole antenna, the radiofrequency system thus having a second radiation pattern having an increased or decreased gain in at least one predetermined direction.

Abstract: An RF device includes a first antenna set made up of a first antenna and a second antenna, the first and second antennas being planar in shape and both lying in a common first plane, the first antenna being arranged to operate in a first frequency band and the second antenna being arranged to operate in a second frequency band; and a first isolator, the first isolator being planar in shape and lying in the first plane between the first and second antennas, the first isolator having at least one branch that is electrically conductive, the first isolator being electrically floating, the first isolator being arranged to reduce first coupling by electromagnetic radiation between the first and second antennas in the first frequency band and/or in the second frequency band.
