<p>The antenna has a group of aligned radiating elements (2) e.g. dipoles, and a reflector (3) comprising a flat part (4) on which the elements are placed. The reflector has lateral edges (5) longitudinally folded on both sides of the elements. A reflecting trap (10) is placed outside a space separating the radiating elements of the folded lateral edges of the reflector. The reflecting trap is formed from an aluminum sheet folded in U shape, where outer surface (11) of one of U- branches cooperates with an outer surface (12) of the lateral edge of the reflector.</p>
