The invention provides a base station antenna adjustment phase shifter stroke transmission device and an antenna. The main points of the technical scheme are that the base station antenna adjustment phase shifter stroke transmission device comprises a supporting seat, the supporting seat is rotatingly connected with a nut, and a screw rod in threaded connection with the nut is disposed in the nut in a penetrating manner. One end of the screw rod is connected with a pull rod which is used for being connected with a phase shifter and can move linearly to change the phase of current flowing through the phase shifter, and a driving mechanism capable of driving the nut to rotate is arranged on the supporting seat. The driving mechanism drives the nut to rotate, and the screw rod drives the pull rod to telescopically move relative to the phase shifter under the screw-thread fit of the nut and the screw rod, so that the phase of the phase shifter is adjusted, the transmission structure is simple, particularly in a multi-band antenna, a space-simplified transmission control form can be realized, and the structural consistency is higher; and the device is more suitable for the development trend of multi-band and miniaturization of the antenna.
Description
technical field [0001] The invention relates to the technical field of phase shift adjustment, in particular to a base station antenna adjustment phase shifter stroke transmission device and antenna. Background technique [0002] In current base station antennas, there are mainly two methods of downtilt adjustment: mechanical downtilt and electric downtilt. The principle of ESC downtilt is to adjust the phase of the phase shifter, thereby changing the phase of the collinear array antenna oscillator, and the amplitude of the vertical component and the horizontal component will change, which will affect the field strength of the composite component, so that the antenna’s vertical The direction map is tilted down. The existing base station antenna adjustment phase shifter stroke transmission device includes a pull rod connected to the phase shifter for changing the phase, and also includes a threaded nut and a screw, the pull rod is connected to the nut, and the nut and the pu...
