The present invention relates to a non-quadrifilar antenna arrangement (10) in a communications apparatus (8) for single, dual and/or multi-band frequency including at least one antenna element (12a-12i, 12b-12j) arranged on at least one surface of a substantially flexible substrate (11) essentially entirely and continuously on said substrate (11) and shaped to a helix. The helix has a first and a second end, said first end being one end of said antenna element at one portion connected to one feeding line and said second end being free radiating. |
