Double-square-loop antenna elements arrayed on dielectric panel. Dichroic microwave reflector consisting of planar square array of double-square-loop copper elements on thin sheet of Kapton (or equivalent) polyimide supported by Kevlar (or equivalent) aromatic polyamid honeycomb sandwich panel. Array and panel designed to reflect most of incident electromagnetic radiation of frequencies between 7.2 and 8.4 GHz (in X band) and to transmit most of that at 2.3 GHz (in S Band) and 13.8 GHz {in K(sub u) band}.
