| Summary: | s c d Disclosed is an extendable swivel antenna, specifically a swivel antenna with enhanced durability, which can prevent deformation of a hinge unit and an outermost antenna covering the hinge unit. The swivel antenna includes: a power feeding unit electrically connected to a terminal ; an antenna unit for transmitting a radio wave received from an external to the power feeding unit , which is folded in multiple stages and can extend; and a hinge unit for connecting between the power feeding unit and the antenna unit and for swiveling the antenna unit , wherein the hinge unit includes an insertion portion connected to the antenna unit , a recess portion connected to the power feeding unit and having a step portion whose diameters of one side and the other side are different from each other, and a hinge pin for fixing the an insertion portion and the recess portion , wherein the antenna unit includes a whip antenna fixed to the insertion portion , one or more road antennas , and to be folded about the whip antenna , and wherein one side of the recess portion whose internal diameter is smaller than that of the other side of the recess portion is housed in the outermost road antenna of the folding one or more road antennas , and |
