Abstract
A deployable lens is provided for an antenna. The lens comprises an array of metallic lens elements formed on a plurality of planar sections of a dielectric substrate, each lens element comprising a first end-fire element directed towards a feed side of the lens, a second end-fire element directed towards a non-feed side of the lens and a section of transmission line for coupling signals between the first and second end-fire elements. The section of transmission line, preferably in the form of a slot-line transmission line, is integrated with the end-fire elements and is of a length determined according to the position of the lens element within the aperture of the lens as deployed. An antenna is also provided comprising a deployable lens according to the present invention.
