ABSTRACT:
A gain structure of antennae of mobile phones including a retractable antenna, an antenna clamping pawl tube element, a connecting fastening ring, and an outer tube. The connecting fastening ring is a double-sleeve tubular element of a shape resembling the numeral "8" with a first sleeve forming a fish-eye hole for receiving a screw which locks the connecting fastening ring to a through hole of a mobile phone to connect the circuits, and a second sleeve forming a screw hole for receiving the antenna clamping pawl tube element. The retractable antenna includes a main tube having a signal collector at its top end, and an auxiliary rod element having a stop bolt at its bottom end and fitted together with the main tube. After the retractable antenna is passed through the antenna clamping pawl tube element, it is fitted with a fine tube which is in turn fitted with the outer tube. The outer tube is adhered to the mobile phone by adhering means. When the mobile phone is in use, the retractable antenna may be pulled upwardly, and the stop bolt of the auxiliary rod element rises to where the antenna clamping pawl tube element is, causing pawl portions thereof stretch outwardly to urge against the wall of the fine tube, whereby the rear end of the antenna may be secured while the main tube may be pulled upwardly to reach an optimum signal reception state. By means of the gain structure of the present invention, mobile phone communication quality may be enhanced.
