Abstract (en)
The subject of the present invention is a phase-shifting system including at least one body (21) which has at least one electrically conductive surface, an electrically conductive feed line (22) placed on the body (21) and including at least two segments (33a-33e, 34a-34e) which are parallel along a longitudinal axis B-B and at least three access points (23, 24a-24e, 25a-25e), a movable dielectric device (26) placed above the feed line (22), characterized in that the device (26) includes two distinct sections (26a-26e) made up of dielectric material, which are capable of moving independently along the longitudinal axis B-B.
