Abstract: The present invention discloses a phase adjustment apparatus. The phase adjustment apparatus includes at least two phase adjustment units, a switching apparatus, and a driving apparatus; where the at least two phase adjustment units are configured to modulate a phase; the driving apparatus is configured to drive the at least two phase adjustment units to move; the at least two phase adjustment units are selectively connected to the driving apparatus; and the switching apparatus is configured to select the at least two phase adjustment units, so that the driving apparatus drives, at a same moment, only one of the at least two phase adjustment units connected to the driving apparatus to move, so as to change a phase. The present invention discloses a multi-frequency antenna which applies the phase adjustment apparatus. The phase adjustment apparatus of the present invention may adjust a downtilt angle of an antenna unit.

Abstract: This application relates to a phase shifter and a remote electrical tilt antenna including the foregoing phase shifter. The metal strip includes a cavity, a metal strip, a sliding dielectric, and a fastener, where the fastener fastens the metal strip in the cavity, so that a transmission portion of the metal strip is suspended in the cavity, requiring no metal strip to be disposed on a substrate, thereby reducing the signal energy loss of the substrate, decreasing the heat generated due to the signal energy loss, and lowering the requirements of the phase shifter on heat dissipation and temperature resistance of an internal mechanical part.
