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 and a second position relative to the first element (404). The performance of the antenna arrangement (402) is substantially less desirable when the second element (406) is between the first and the second position than the performance of the antenna arrangement (402) when the second element (406) is at either the first or the second position. The second element (406) is mechanically spaced apart from and substantially electrically coupled to the first element (404) in both the first and the second position. The antenna arrangement (402) advantageously provides for reduced dimensions while achieving desirable performance.

The first element (4 04) is coupled to circuitry (408) of the wireless communication device (400). The se cond element (406) is movable between a first position (see Fig. 4) and a second posi tion (see Fig. 5) relative to the first element (404). The second element (406) is ca pacitively 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 elem ent (406) is moved to the second position. Further, a variable reactance tuner (505), ope ratively coupled to the antenna element (406), variably tunes the reactance of the antenn a element (406) when the antenna element (406) is moved between the first position and the second position.
