Abstract

An antenna arrangement (402) for a wireless communication device (400) comprises a first element (404) and a second element (406). The first element (404) is coupled to circuitry (408) of the wireless communication device (400). The second element (406) is movable between a first position (see Fig. 4) and a second position (see Fig. 5) relative to the first element (404). The second element (406) is capacitively coupled to the first element (404) when the second element (406) is moved to the first position and inductively coupled to the first element (404) when the second element (406) is moved to the second position. Further, a variable reactance tuner (505), operatively coupled to the antenna element (406), variably tunes the reactance of the antenna element (406) when the antenna element (406) is moved between the first position and the second position.
