Abstract

An antenna (100,200,300, 400, 500) comprising first (110, 210, 310, 410, 430) and second (120, 220, 320, 420, 440) structures for guiding electromagnetic waves, each comprising groups (111, 130, 150, 230, 330; 140,160, 240, 340, 445, 470) of radiation elements. For adjacent sections in 5 the structures, at least one applies: ?Groups of radiation elements are distributed along the two structures such that a group (110, 130, 150) in the first structure overlaps a group (120, 140,160) in the second structure partially or not at all. ?Radiation elements within said groups (230; 240) exhibit a common 10 main direction of extension within the group, and differs between the first and the second groups by an angle of at least 10 degrees. ?The radiation elements of the groups (330, 340) are distributed along the structures (310, 320) on sides of the structures which face different directions.
