Abstract: The present invention relates to an antenna arrangement comprising means (1, 72, 72', 77, 77') for providing an approximation of a constant current electrical loop, which is arranged to provide a first essentially toroid-shaped radiation pattern (29), where the antenna arrangement further comprises a first (67) and a second (68) electrical dipole. The electrical dipoles (67, 68) are arranged essentially orthogonal to each other, and are arranged to provide a second (30) and third (31) essentially toroid-shaped radiation pattern which each is essentially orthogonal to the other and to the first essentially toroid-shaped radiation pattern (29). The means (1, 72, 72', 77, 77') for approximation of the constant current electrical loop comprises at least two current path parts (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76'), where a current (I1, 12, 13, 14) can be applied to each one of said parts (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76'), so that the current (11, 12, 13, 14) in each one of said parts (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76') essentially will be in phase with each other.
