Abstract
A dual band antenna element suitable for use in a compact multiband antenna array is described. The dual band antenna element may have a main radiating direction with a first radiating element for use in a first frequency band, a first electrically closed ring for use in the first frequency band galvanically isolated from and arranged at a predetermined distance from the first radiating element in the main radiating direction. The first ring) may at least partially overlap the first radiating element in the main radiating direction. The dual band antenna element may also have a second radiating element for use in a second frequency band, where the second radiating element is arranged within a circumference of the first radiating element and is arranged substantially at the predetermined distance (D) from the first radiating element in the radiation direction.
