  • Patent number: 9825607
    Abstract: The present invention relates to a phase-shifting unit module, a manufacturing method therefor, a phase shifting device, and an antenna. The phase-shifting unit module comprises a first metal ground plate, a second metal ground plate, an insulating dielectric plate, a slide apparatus, and a fixed transmission line. The insulating dielectric plate is provided thereon with at least one impedance transforming part. The thickness of the impedance transforming part is less than the thickness of the remaining parts of the insulating dielectric plate. The impedance transforming part of the insulating dielectric plate is overlapped with the fixed transmission line during a moving process. The insulating dielectric plate is overlapped only with the fixed transmission line, thus reducing reflected signals, while at the same time reducing losses, and facilitating ultra-wideband design of the phase-shift unit module and of the phase-shifting device.
