Abstract: A CWUSB, ExpressCard card has a body with an internal slide in the form of a deep rectangular slot. Accommodated in the slot is an aerial unit in two parts pivotally connected together. The slot has sides to the slot and slightly over-hung ends. The first part has a major portion with a width to slide in the slot and a minor portion with a reduced width that is able to protrude between the over-hung ends in an extended position of the aerial unit. The minor portion has pivot points. The second part is longer and has the reduced width whereby it can pass between the overhung ends. The inner end of the second part has complementary pivot points, whereby the parts are pivotally connected. The parts molded to locate a torsion spring, which biases the second part upwards with respect to the first part.
