PROBLEM TO BE SOLVED: To cope with the problem of isolation between two antennas. SOLUTION: The present invention relates to an antenna system comprising, on a substrate (3), at least first and second printed radiating elements(1) and (2), supplied by feed lines (4, 5) with at least one transmission line (10) comprising a first extremity (10a) and a second extremity (10a) between the two radiating elements. The first tip and the second tip of the transmission line are coupled to the first and the second radiating elements, respectively, according to a coupling function with a ratio 1:b, b>1 and a phaseΦlinked to the physical difference between the radiating elements, the length of the transmission line bringing a phase differenceΘso that the phaseΦis compensated.
