Abstract (en)
[origin: EP0487387A1] The antenna of the invention has a "suspended three-plate" structure having two metal plates (26, 27) embracing a dielectric film (28). A channel for a supply line (31) of a slot (34) is made in this structure, the end of the central conductor (32) of the line penetrating into a cavity whose thickness is substantially equal to that of the channel, the slot being made in the upper wall of the cavity. <IMAGE>
