The invention relates to a glazing including a glass sheet, one surface of which is covered with a conductive layer. Said glass sheet comprises, at a nonzero distance from the conductive layer, a periodic pattern of conductive elements that is suitable for increasing, for a predetermined frequency, the transmission of radiofrequency electromagnetic waves. Said periodic pattern is selected so as to have a transmission zero at a frequency of between substantially half and substantially double the frequency to be amplified.

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&#xb0; and define an arrowhead pointed toward the outside, wherein the arms () corresponding to two separate segments () do not intersect.
