  • Patent number: 8043678
    Abstract: The present invention relates to a radome which has excellent transmission loss of radio waves and structural strength, which can be easily produced, and which has favorable workability, and a method of producing the same. The radome includes an olefin woven material and a glass cloth, in which the olefin woven material and the glass cloth are impregnated with a matrix resin to be integrated with each other, and the glass cloth is disposed closer to an inner side of the radome than the olefin woven material. As the olefin woven material, a woven material formed of an ultrahigh molecular weight polyethylene fiber can be used. As the matrix resin, an epoxy resin, a vinyl ester resin, an unsaturated polyester resin, or a silicone resin can be used.
