| 摘要 |
The invention relates to antenna technique and may be used in radio systems, aerospace systems and complexes comprising antennas. An antenna reflector comprises odd conducting concentric ring surfaces located in the same plane on radio-transparent basis made as a cell structure performed as identical prisms and has aperture function, the inner diameter of cell prism hexagon is less than a half of a signal wave length, width of connecting surface of edges is equal or more than 0, 05 length of signal wave and covered with conducting material. Usage of the invention provides loss of construction mass, decrease of sizes, therefore costs of transportation with keeping the same parameters of Fresnel zone antenna, in particular an amplification factor. |
