Abstract
Multi-element microwave plane antenna for receiving satellite television signals with two simultaneous polarizations. The antenna is provided with two systems of lines (1) whose ends (3, 30) form probes emerging into wave-guides (2). The probes of one system (3) are perpendicular to those of the other system (30). Between the two systems of lines there is placed only a thin sheet (150) bored with cross-shaped cut-outs (6), and provided with separating studs made from a silk-screen-printed insulating material.
