Abstract (en)
[origin: EP0109186A1] An antenna (1) including a reflector (2) having a paraboloidal front surface (8) and a primary radiator (3). The reflector (2) of the antenna comprises a reflecting layer (9) having the paraboloidal front surface and the backing layer (10) attached to the rear surface of the reflecting layer (9). The reflecting layer is made of a resin in which short carbon fibers (7) are randomly dispersed with the axis of each fiber substantially parallel to the paraboloidal front surface. The antenna thus constructed has nearly isotropic electro-conductivity and excels in durability.
