Problems solved by technology
The existing downtilt of the multi-band antenna can be realized through the shifting components; however, this type of structure has a high degree of integration, and all the power inputs form a circle, and at the same time, the phase shifter on the back of the antenna needs to be concentrated in the middle of the antenna to shift the phase. The device needs to be stacked in multiple layers, the structure is complex, the design and processing are difficult, and the installation is complicated

Description
technical field [0001] The present application relates to the technical field of mobile communication base station antennas, and in particular to a downtilt angle adjustment device and an electronically adjustable antenna. Background technique [0002] In the mobile communication system, in order to optimize the wireless signal covered by the service area and to suppress the mutual interference of the same frequency signals, it is necessary to adjust the downtilt angle of the mobile communication base station antenna reasonably. The electrical downtilt angle adjustment is to continuously adjust the antenna feed network and continuously change the phase of each oscillator in the antenna array through the phase shifter, a key component of the antenna, so as to realize the continuous adjustment of the antenna electrical downtilt angle. [0003] At present, there are mainly two methods for adjusting the electric downtilt angle of the antenna, one is mechanical downtilt, and the ...
