Abstract
The present invention relates to an antenna system comprising on a substrate, at least a first and a second printed radiating elements, each supplied by a feed line, with, between the two radiating elements, at least one transmission line comprising a first extremity and a second extremity. The first and the second extremities of the transmission line are respectively coupled to the first and the second radiating elements according to a coupling function with a ratio 1:b, b>1 and a phase φ, linked to the physical difference between the radiating elements, the length of the transmission line bringing a phase difference θ such that θ compensates for φ. The invention applies to antennas compatible with WIFI.
