    摘要: An arrangement and method for hybrid beamforming includes a differential phase shifter. The phase shifter has substantially parallel elongate conductive input and output radio frequency transmission lines. A movable transverse planar conductive coupling element configured to provide capacitive coupling between itself and the input and output lines. The coupling element is slideably movable along an axis of the said input and output transmission lines.

    摘要: A repeater has a spherical dielectric lens antenna, a donor feed unit supporting transmission and reception of signals through the lens antenna, a service feed unit supporting transmission and reception of signals through the lens antenna, and at least one interconnecting guided transmission medium providing a radio frequency transmission path between the donor feed unit and the service feed unit.
