Abstract:
1. An antenna for a wireless device comprising: a main body; a first strip; a second strip; wherein the first strip and the second strip extends from the main body for constituting at least two contact elements for connecting the main body to at least two contact elements of said wireless device; wherein the first strip, the second strip and said main body are formed out of a same plate of electrically conductive material; wherein the first strip comprises a first free end and an end connected to the main body at a first point of transition between the main body and the first strip; wherein the second strip comprises a second free end and an end connected to the main body at a second point of transition between the main body and the second strip; wherein the antenna is configured so that when said plate is made flat with the first strip, the second strip and said main body lying on a same plane, then a first area being an area of a smallest possible rectangle that encompasses a perimeter of the main body and that of said first strip and said second strip and a second area being an area of a smallest possible rectangle that encompasses the perimeter of the main body, are identical; wherein the antenna is configured so that when said plate is made flat with said first strip, said second strip and said main body lying on a same plane, then said main body comprises within said second area, a gap in the main body, said first strip extending into said gap from a first edge of said main body that delimits said gap; wherein a distance along a longitudinal direction of the first strip and away from the gap between said first point of transition and a first side of a perimeter of the second area is smaller than a distance between said first point of transition and a midpoint between two opposite sides of the perimeter of the second area along said longitudinal direction, so that the first strip extends from said first edge towards a more central portion of the main body; wherein the electrically conductive material of the main body extends continuously along said longitudinal direction between said first point of transition and said first side, so that when the first strip is folded about said point of transition, the free end is proximate to said first side; wherein one strip of the first strip and the second strip serves as a contact element for feeding the antenna; and wherein the other strip of the first strip and the second strip serves as a contact element for connecting the antenna to ground.
