Abstract:
An antenna configuration, comprising:an antenna having first convex-curved antenna elements, second convex-curved antenna elements, a third antenna elements and webs; said first convex-curved antenna elements having a first curvature, said second convex-curved antenna elements having a second curvature, said first and second convex-curved antenna elements being disposed in an alternating pattern such that said first curvature and said second curvature are curved in opposite directions; said first and second convex-curved antenna elements having respective adjacent ends; said antenna defining a longitudinal direction, said webs extending in the longitudinal direction and connecting said respective adjacent ends of said first and second convex-curved antenna elements such that said first and second convex-curved antenna elements are connected in series without overlapping one another in the longitudinal direction and such that said first and second convex-curved antenna elements form a helical configuration; and said third antenna elements being connected to said first and second convex-curved antenna elements and extending in the longitudinal direction and essentially parallel to said helical configuration formed by said first and second convex-curved antenna elements.
