Abstract:
A planar antenna comprising a planar radiating element (600) which is formed of a conductive area confined by a substantially continuous border line and split by a non-conductive gap which divides the planar radiating element into a first branch and second branch such that both the first branch and the second branch have respective outermost ends, an outermost end being defined as that part of a branch that is the electrically farthest point from a feed point where a local electric field maximum is generated when said antenna is in use, said gap has a head end on said substantially continuous border line and a tail end within the conductive area, the antenna operating in two frequency bands characterized in that at said head end (601) the gap has a certain first direction and at said tail end (603) a certain second direction which differs from the first direction by more than 90 degrees when the directions are defined along the gap from the head end towards the tail end, whereby the outermost end of the second branch confined by the gap, is located within the continuous border line surrounded by the first branch.
