Abstract
The invention relates to a surface suitable for filtering a plurality of frequency bands, said surface including a set of separate identical basic conductive units () that are reproduced in a periodic arrangement on a dielectric substrate (). The basic unit includes: a tripole consisting of three identical segments () that extend radially from a center (); and two arms () that extend symmetrically from an intermediate point of each segment, said intermediate point being located at a common distance (D) from the center () for each of the segments (). The general directions of both arms form an angle of approximately 120° and define an arrowhead pointed toward the outside, wherein the arms () corresponding to two separate segments () do not intersect.
