Abstract:
     The invention is a frequency selective surface based on integrated waveguide technique, able to act as a frequency band multiplexer applied to multifrequency antennas of satellite, radar and other communication systems, act as radar antenna cover used for stealth technique, and be applied to manufacture multiplexed auxiliary surface of a multiplexed antenna in millimeter wave-infrared compound remote sensing technique and polarizers and beam separators in optical and quasi-optic systems. And it is carved with many corresponding double-layer periodic clearance channel units on double metallic sides of a dielectric substrate to compose an array of double-layer clearance channels, and periodically and at intervals arranges a series of metallized through holes around each double-layer periodic clearance channel unit on the substrate to form a substrate integrated waveguide cavity equivalent to a traditional metal cavity. As compared with ordinary pasted or slotted frequency selective surface, it has better pass band and better angle of incident wave and stability of polarity.
