Claims

[Scope of utility model registration request]

In an antenna phase shifter that is interposed in the middle of an antenna element to form an LC resonant circuit between upper and lower antenna elements, the phase shifter is divided in the axial direction of the antenna element and has a plurality of connections to each other. A plurality of phase shifter units are connected in a connector manner through pins and pin receivers, and each phase shifter unit has a conductive metal member facing each other so as to function as a capacitor in a connected state, and is connected to the connecting pin. 1. A phase shifter for an antenna, characterized in that the pin holder is configured to form a loop circuit to form a coil between each conductive metal member.
