The invention relates to a parabolic antenna reflector. The reflector is comprised of two metal layers (2, 4) which are separated by a dielectricum (3) consisting, for instance, of polypropylene plastic. For the purpose of eliminating the edge currents which occur in the signal receiving and signal transmitting metal layer of the reflector, the reflector is constructed to form a capacitor, wherewith the insulating layer (3) is given a thickness such that in conjunction with the dielectric constant of the selected insulating material the side lobes, created by the edge currents are at least substantially eliminated. |
