Abstract
A phase shifting device, an antenna unit and abase station are disclosed. According to an embodiment, the phase shifting device comprises a power divider and a phase shifter. The power divider comprises an input inlet for an input signal, a first output outlet connected with an impedance member having a system impedance, and a second output outlet connected with the phase shifter. The phase shifter comprises a first plate and a second plate slidable relative to the first plate. Two parallel microstrip lines are provided on a first surface of the first plate. An adjusting member is provided on a second surface of the second plate that faces to the first surface of the first plate. The adjusting member is configured to adjust a length of a total signal transmission path that is from one to the other of the two parallel microstrip lines via an intermediate signal transmission path introduced by the adjusting member, or to prohibit the input signal from transmitting to the second output outlet, according to a position of the second plate relative to the first plate when the second plate slides relative to the first plate.
