This invention relates to the field of base station antenna technology and provides a low-loss sheet metal phase shifter, comprising a cavity shell, a sheet metal network, a phase-shifting medium, a supporting medium, and an RF connector. The cavity shell has through-holes on both sides. Inside the cavity shell are two isolated inner cavities, each with a set of sheet metal networks. The phase-shifting medium and the supporting medium are respectively located on both sides of the sheet metal networks. The phase-shifting medium can slide back and forth along the length of the sheet metal network. The supporting medium has at least one hollow unit, which is uniformly distributed along the thickness direction of the supporting medium. The supporting medium is made of a low-dielectric-constant, low-loss insulating material. The RF connector passes through the side wall of the cavity shell and is electrically connected to the sheet metal network. Therefore, the low-loss sheet metal phase shifter of this invention reduces signal transmission loss, is energy-efficient, and has a stable and reliable structure.
