Abstract
A confocal parabolic antenna system includes a grid of parallel metallic strips placed in the focal plane of the antenna system. The strips are oriented in the direction of an uplink wave polarization and eliminate the grating lobes at the uplink frequency band by reflecting the energy of the particular spatial harmonic components which give rise to the grating lobes.
