A wideband frequency selective surface 10 is disclosed which includes a square grid 12 having a first plurality of parallel conductive lines perpendicularly intersecting a second plurality of parallel conductive lines to provide a plurality of squares. The distance between the parallel conductive lines is p. A plurality of conductive square loops 20-23 are included within the plurality of squares. The distance between each line segment of each square loop and the corresponding adjacent parallel conductive line segment of the square grid is g. The distance g is greater than one quarter times the distance p for wideband performance.
