    摘要: Sliding phase shifters for use in phased array antennas are disclosed. According to one aspect, a sliding phase shifter includes a fixed dielectric having first striplines to couple power into the sliding phase shifter. The sliding phase shifter also includes a sliding dielectric having second striplines electrically slidingly coupled to the first striplines. An amount of phase shift is determined by an amount of overlap of the first striplines and the second striplines, a width of the second striplines being at least partially tapered along a portion of the second striplines to improve performance.

    摘要: Embodiments of the present disclosure relate to a phase shifter, an antenna device and a base station. The phase shifter comprises: a substrate comprising first conductive members, a movable assembly, and an adjusting assembly. The movable assembly comprises a second conductive member electronically coupled to first conductive members, and is adapted to move relative to the substrate in a first direction to shift a phase of an electrical signal output by the phase shifter. The adjusting assembly is coupled to the movable assembly and adapted to move the movable assembly to enable an alignment of the second conductive member and the first conductive members; or a change of a force applied by movable assembly to the substrate. In this way, the phase shifter is provided with an error-adjustment mechanism, and the antenna device as well as the base station including these phase shifters can achieve an increased accuracy and consistency.
