Abstract

An antenna arrangement comprises a dual-polarised turnstile antenna, which comprises a first and a second dipole antenna element, which are aligned perpendicular to one another. The first and second dipole antenna elements each comprises two dipole halves. The dipole halves of both dipole antenna elements comprise a dipole section and a coupling section, which are galvanically connected to each other and to a first end of a ground connection medium or a signal connection medium. The coupling sections each extend along the closest dipole section of the adjacent other first and/or second dipole antenna element, wherein a spacing gap is formed between a coupling side of the respective coupling section of the first and/or second dipole antenna element and the respective adjacent dipole section of the second and/or dipole antenna element.
