ABSTRACT:
A frequency-selective surface structure for narrow-band filtering of electromagnetic waves, comprising a fully wave-reflective surface perforated by H-shaped slot elements each consisting of end limiting bars and a connecting bar extending transversely with respect to the limiting bars. The end limiting bars of the individual slot elements each have essentially the same length as the connecting bar and have a bar length of approximately one fourth of the operating wave length.
