ABSTRACT:
The present invention relates to an antenna arrangement comprising a constant current electrical loop, which is arranged to provide a first essentially toroid-shaped radiation pattern, where the antenna arrangement further comprises a first and a second electrical dipole. The electrical dipoles are arranged essentially orthogonal to each other, and are arranged to provide a second and third essentially toroid-shaped radiation pattern which each is essentially orthogonal to the other and to the first essentially toroid-shaped radiation pattern. The constant current electrical loop comprises at least two current path parts, where a current can be applied to each one of the parts, so that the current in each one of the parts essentially will be in phase with each other.
