Claims

[Scope of Claim for Utility Model Registration] (1) Antenna elements with radiating elements embedded therein are concentrically and slidably fitted together, and a contact point is provided on the outer peripheral surface of the proximal end of the protruding antenna element; The contact and the radiating element are connected through a phase shifter buried inside, and the tip of the radiating element of the antenna element on the side that supports the antenna element on the protruding side is configured to be able to contact the contact in an extended state. A collinear array antenna for mobile radio equipment. (2) The antenna elements with the radiating elements embedded therein are concentrically and slidably fitted together, and the coupling ring with the phase shifter embedded is slidably fitted into both the protruding side and supporting side antenna elements. A collinear array antenna for a mobile radio device, characterized in that the radiating element on the protruding side and the phase shifter are connected to each other, and the phase shifter and the radiating element on the support side are connected only in the extended state.
