Abstract

The present invention relates to a multiple frequency band antenna means for transmitting and/or receiving RF signals. The antenna means comprising a ground plane means arranged to be connected to ground of a circuitry of a radio communication device and a conductive radiating structure (2, 3 and 4) having a first arm (2) and a second arm (3). Said second arm (3) having a length different from that of the first arm (2). Said first arm (2) and said second arm (3) being electrically connected by a bridge (4), where said bridge (4) being means for matched feeding of said second arm (3) at a second frequency. A dielectric is separating said radiating structure (2, 3 and 4) and said ground plane means. A first end (21) of said first arm being a feed portion (5) and a second end (22) of said first arm (2) being a free end. A first end (33) of said second arm (3) being electrically connected to a frequency tuning arm (35) for said second frequency in said second arm (3) and a second end (34) of said second arm (3) being a free end, where said first and second arms (2 and 3) are forming an angle with said frequency tuning arm (35).
