A multi-band antenna for use in a portable telecommunication apparatus (1) has a pattern (11) of thin conductive material and is adapted to operate in at least two, preferably at least three, frequency bands, such as 900 MHz, 1800 MHz and 1900 MHz. A first portion (13) of conductive material has a first end (12), which is connected to radio circuitry (10) in the portable telecommunication apparatus. It also has a second end. A second portion (14) of conductive material has a first end, which is connected to the second end of the first portion. The second portion has a non-linear extension and is narrower than the first portion. A third portion (16) of conductive material is connected to the second portion (14). The third portion is wider than the second portion and provides capacitive loading of the antenna.
