ABSTRACT:
An antenna module (1) for a mobile phone in accordance with the present invention includes an antenna (2), an elastic element (3) and a feed mechanism (5). The elastic element surrounds a lower part (21) of the antenna and pushes the antenna outwardly. The feed mechanism has a connecting means (50) and a guiding groove (52). The connecting means movably engages with the antenna and slidably engages with the groove. The movement of the antenna between an extended position and a retracted position is regulated by engagement between the connecting means and the groove, and is aided by the resilience of the elastic element. A user can move the antenna between a retracted position and an extended position using one hand.
