A SIW ANTENNA ARRANGEMENT

摘要

An antenna arrangement (1) comprising a SIW (2) with at least one radiating arrangement (3). The SIW comprises a dielectric material (4), a first and second metal layer (5, 6) and a first and second electric wall element (7a, 7b) running essentially parallel and electrically connecting the metal layers (5, 6). For each radiating arrangement (3), the antenna arrangement (1) comprises at least one coupling aperture (8) in the first metal layer (5), and for each coupling aperture (8) there is a third wall element (7c) running between the first and second electric wall elements (7a, 7b), across a SIW longitudinal extension (es). For each radiating arrangement (3), the antenna arrangement (1) further comprises an at least partly electrically conducting antenna component (9) which comprises at least four radiating elements (10a, 10b, 10c, 10d) and is surface-mounted on the first metal layer (5), enclosing at least one coupling aperture (8). For each radiating arrangement (3), electromagnetic signals are arranged to be transmitted between said coupling aperture (8) and said radiating elements (10a, 10b, 10c, 10d).
