    • The present invention relates to an antenna device for wireless transmission and reception of information using electromagnetic signals, comprising at least two dipole antenna elements (1; 1a, 1b, 1c; 1', 1", 17a, 17b), where each dipole antenna element (1; 1a, 1b, 1c; 1', 1"; 17a, 17b) comprises a first dipole arm (2; 2a, 2b, 2c; 2’, 2"; 2'a 2"a 2'b 2"b 2'c, 2"c 2'd, 2"d, 2'e 2"e, 2'f, 2"f, 2'g, 2"g, 2'h, 2"h, 2'i, 2"i; 22a, 22b) and a second dipole arm (3; 3a, 3b, 3c; 3', 3"; 3'a, 3"a, 3'b, 3"b, 3'c, 3"c, 3'd, 3"d, 3'e, 3"e, 3'f, 3"f, 3'g, 3"g, 3'h, 3"h, 3'i, 3"i; 23a, 23b), which first and second dipole arms are extending in essentially opposite directions from a respective feeding point (4, 5) end. The dipole arms are formed in metal layers on a laminate (9; 18; 30, 31, 32; 33, 34, 35), having a first side (10, 19) and a second side (11, 20), which laminate (9; 18; 30, 31, 32; 33, 34, 35) further has a predefined thickness (T) separating the first (10, 19) and second (11, 20) side. Each first dipole arm (2; 2a, 2b, 2c; 2', 2"; 2'a, 2"a 2'b 2"b 2'c 2"c, 2'd 2"d, 2'e, 2"e, 2'f, 2"f, 2'g, 2"g, 2'h, 2"h, 2'i, 2"i; 22a, 22b) extend on the first side (10, 19) of the laminate (9; 18; 30, 31, 32; 33, 34, 35) and each second dipole arm (3; 3a, 3b, 3c; 3', 3"; 3'a, 3"a, 3'b, 3"b, 3'c, 3"c, 3'd, 3"d, 3'e, 3"e, 3'f, 3"f, 3'g, 3"g, 3'h, 3"h, 3'i, 3"i; 23a, 23b) extend on the second side (11, 20) of the laminate (9; 18; 30, 31, 32; 33, 34, 35) in such a way that the two adjacent dipole arms (3a, 2b; 3b, 2c; 2'a, 3'b; 3'b, 3'c; 3"a, 2"d; 3"b, 2"e; 3"c, 2"f; 2'd, 3'e; 2'e, 3'f; 3"d, 2"g; 3"e, 2"h; 3"f, 2"i; 2'g; 3'h; 2'h, 3'i; 23a, 22b) of adjacent antenna elements (1 a, 1b, 1 c; 17a, 17b) partially overlap during a distance (D).
