Abstract:
1. An antenna device comprising: at least two radiating arms; a ground plane; a first arm of the at least two radiating arms includes first and second ends and a feeding point at the first end; a second arm of the at least two radiating arms includes first and second ends and a grounding point at the second end; wherein the at least two radiating arms are coupled by at least one close proximity region, said at least one close proximity region being formed by a portion between said two arms in which a distance between at least a first point in said first arm and at least a second point in the second arm is smaller than a distance between said feeding point and the grounding point and the at least one close proximity region does not intersect a projection orthogonal to the ground plane; wherein the antenna does not include a contact point between said first arm and said second arm; and wherein said antenna is a monopole antenna.
