Abstract
Abstract A mobile telephone antenna including an alloy wire rod moved in a metal socket in a mobile telephone at the top, the alloy wire rod having a bottom end fixed with a first axial metal element, and a top end inserted through a second axial metal element, which is mounted in a stepped locating member inside an antenna cap, an insulative sleeve mounted around the top section of the stepped locating member and defining a space on the inside above the top section of the stepped locating member, a matching coil mounted around the stepped locating member and the insulative sleeve and stopped between the bottom section of the stepped antenna and the inside wall of the antenna cap, and a contact terminal fixedly fastened to the top end of the alloy wire rod and moved in the space between a first position in which the antenna terminal disposed in contact with the second axial metal element and the stepped locating member and the mobile telephone antenna is collapsed, and a second position in which the antenna terminal is disconnected from said second axial metal element and the stepped locating member and the mobile telephone antenna is extended out.

Claim 1
Independent Claim
338 words
A mobile telephone antenna mounted in a metal socket at a top side of a mobile telephone, comprising an alloy wire rod inserted through said metal socket and having a bottom end and a top end, said bottom end being fixedly fastened to a first axial metal element and said top end being inserted through a second axial metal element, an antenna cap, a stepped locating member fixedly mounted inside said antenna cap around the top end of said alloy wire rod, said stepped locating member comprising bottom section, a middle section, and a top section, the diameter of said middle section being bigger than said top section and smaller than said bottom section, an insulative sleeve mounted around the top section of said stepped locating member and defining a space on the inside above the top section of said stepped locating member, a matching coil mounted around the middle section of said stepped locating member and said insulative sleeve within said antenna cap and retained between said stepped locating member and said antenna cap, and a contact terminal having a head disposed outside the top section of said stepped locating member, said contact terminal being fixedly fastened to the top end of said alloy wire rod and moved in said space between a first position in which said head of said contact terminal is disposed in contact with the top side of said stepped locating member when said mobile telephone antenna is fully extended, and a second position in which said head of said contact terminal is disconnected from said second axial metal element and said stepped locating member when the mobile telephone antenna is collapsed and also when the mobile telephone antenna is collapsed said second axial metal element and said bottom side of said locating member are disposed in contact with said metal socket whereby a radio signal is directly received by said metal socket when said antenna is collapsed and said locating member receives a radio signal directly when said antenna is fully extended.
