Abstract
An antenna device for receiving and/or transmitting dual polarized electromagnetic waves, comprising at least one antenna element (7). There are disposed parasitic elements (8, 9) of an electrically conductive material in a region, which surrounds the antenna element and includes the space between and including two parallel planes (2, 1) being defined by a ground plane layer (2) and the antenna element (7), respectively. Each parasitic element (8, 9) comprises at least one elongated, longitudinal portion, extending along an associated lateral side of the antenna element.
