<P>PROBLEM TO BE SOLVED: To provide a horn antenna capable of achieving more weight reduction and higher dimensional stability and higher manufacturability than a conventional metal horn antenna by using a composite material formed from carbon fiber and resin as a structural member of the horn antenna. <P>SOLUTION: The horn antenna is formed from compression molding by using, as a molding material, a composite material of a mixture of chopped fiber and resin finely cut into a strip shape. A coating layer formed from metal material is provided on a surface of the horn antenna to provide conductivity required for the antenna. <P>COPYRIGHT: (C)2013,JPO&INPIT |
