Abstract:
    This invented super thin single-side steep filter property frequency selection surface can be used in multiple frequency antennas of satellite, radar communication system as a frequency band multiplex machine, which is processed on a multi-layer chip with three-layers of metal faces and two dielectric layers formed by laminating two microwave plate layers, in which, the top and bottom metal surfaces are etched with periodic large square loop slots in the same size, another size of periodic small square loop slot coincident with the central position of the large one is etched on the middle metal side, two media layers are filled among the three metal surfaces, a serial metal through holes in even intervals around each of the slot unit on the laminated multi-layer chip to form a chip integrated waveguide cavity equivalent to traditional metal cavities.
