An antenna for a portable communication apparatus has a radiator with first and second ends, the first end being connected to radio circuitry in the portable communication apparatus. The antenna also has a feedback conductor having a first end that is connected to the second end of the radiator. The feedback conductor extends along the radiator in a first direction from the second end of the radiator towards the first end of the radiator. A second end of the feedback conductor extends along the radiator in a second direction from the first end of the radiator towards the second end of the radiator, for tuning the frequency of the antenna.
