Abstract
A planar high-frequency antenna having radiating elements for high-frequency signals includes at least two facing conductive plates provided with oppositely-arranged openings which cooperate to form respective cavities. Disposed between each pair of facing plates is a thin dielectric sheet supporting an array of strip conductors of coaxial lines forming suspended-substrate microstrip lines with these plates. Ends of the strip conductors extend into the cavities and form radiating elements. Each thin dielectric sheet is held in place between the facing plates by means of positioning spacers provided on the faces of these plates. The spacers are located in areas where there are no conductors on the dielectric sheet and are sufficiently remote from each other such that at least two cavities and/or lines of the network of strip conductors are located between any two spacers.
