An antenna structure includes an insulating substrate 101, 107 a conductive sheet 102 formed on the insulating substrate, a first radiative element 104 and a second radiative element 105 wherein each of the radiative elements includes a first strip portion 404 for example a linear strip portion extending away from the conductive sheet, and a second strip portion 403 connected to the first strip portion and extending from the first elongate strip portion at an angle thereto, e.g. at an angle of ninety degrees, wherein the first and second radiative elements are formed on opposite faces of the substrate in adjacent regions 106, 107. When the antenna structure is arranged horizontally, the adjacent regions may lie one 106 over the other 107 and the first and second portions of the first radiative element may lie over the first and second portions of the second radiative element. The antenna structure may conveniently be in the form of a plate-like module formed on the substrate. |
