The invention relates to the field of antennas for mobile communication base stations, and discloses an electric adjustable antenna, which includes a synchronous phase-shifting transmission mechanism; the synchronous phase-shifting transmission mechanism includes at least one connecting plate; any connecting plate is connected to multiple phase shifters at the same time, and the connecting plate A driving structure is connected, and the driving structure is used to drive the connecting plate to move back and forth along a straight line. The electronically adjustable antenna provided by the present invention is provided with the same connecting plate connected to multiple phase shifters, which can effectively drive multiple phase shifters for synchronous movement and adjustment; and the plate-shaped feature of the connecting plate can reduce the space required for transmission , which has more advantages in thickness and space; the transmission mechanism is simple, so that the transmission accuracy and consistency of the electric adjustable antenna are high, and the synchronization of the multi-phase shifter movement is better, which is more in line with the trend of thinner and thinner antennas.
Description
technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to an electrically adjustable antenna. Background technique [0002] In order to meet the needs of future high-speed mobile broadband communications, the fifth-generation cellular mobile communications—5G, with its high data rate, low delay, energy saving, high system capacity and other performance advantages has become an inevitable trend in the development of mobile communications. In order to further improve the universality and matching of 5G base station system applications, the large-scale radiating element array of 5G base station antennas also needs to realize the adjustment of the electrical downtilt angle. [0003] However, in order to adjust the electrical downtilt angle of the 5G base station antenna, multiple phase shifters are required for synchronous adjustment. Due to the high frequency of use of the 5G base station antenna, the adjustment of...
