Claim:
1. An apparatus comprising: a first antenna element having only one galvanic connection, the only one galvanic connection being physically connected to a first feed point, the first antenna element having a first electrical length, the first antenna element being a planar inverted L antenna element, the first antenna element being configured to resonate within a first resonant frequency band; a second antenna element having only one galvanic connection, the only one galvanic connection being physically connected to a second feed point, different to the first feed point, the second antenna element being a planar inverted L antenna element, the second antenna element including: a first portion extending from the second feed point towards the first antenna element to enable the first portion to electromagnetically couple with the first antenna element, and having a second electrical length configured to enable the first portion of the second antenna element to resonate within a second resonant frequency band, the first resonant frequency band and the second resonant frequency band having at least partially overlapping frequencies; and a second portion which extends from the second feed point and has a third electrical length, different to the first electrical length of the first antenna element and to the second electrical length of the first portion, wherein the second portion of the second antenna element is operable to resonate within a third resonant frequency band, different to the first resonant frequency band and to the second resonant frequency band, wherein the first antenna element and the second antenna element provide an antenna arrangement for a portable electronic device.
