    • The present invention relates to a mobile communication terminal antenna with improved operational reliability. The antenna mounted on a mobile communication terminal comprises: an antenna base, which is formed in a rod shape having a circular cross section and has three connected parts extending from one end in an axial direction spaced apart at a distance from each other, each connected part having a through hole to pass the other connected parts therethrough concentrically; two connecting members to be inserted between the connected parts, respectively, each connecting member having, at one end, an insertion portion with a through hole to pass the other therethrough concentrically; a connection pin press-fitted into the through hole of the connected part and the through hole of the insertion portion to fasten the connecting member to the antenna base in a rotatable manner; and a longitudinally elastic telescopic pipe to which the connecting member is fastened. According to the present invention, it is possible to maintain conductivity between the insertion portion and the connected part even after tens of thousands of bending tests or a long-term use, as well as the position-retaining capability of the antenna during the bending, thereby improving the reliability of the antenna and reducing a defect rate.

    • The present invention concerns a telescopic mast (1) which at least includes one or more telescoping joints (2), where a telescoping joint consists of two telescoping sections dimensioned so that one section can be moved into another section, where between each of two adjacent telescoping sections in a telescoping joint there is provided at least one actuator (6) urging the adjacent telescoping sections away from each other, where these actuators are disposed internally of the telescoping joints and offset at the internal periphery. By disposing actuators offset at the inner periphery of the telescoping sections, several advantages are achieved. The actuators are provided at a protected location, and the actuators may be designed with lengths overlapping each other when the telescopic mast is collapsed.
