Description

[technical field] [0001] The invention relates to the field of wireless communication base station antennas, in particular to an optimally designed electrically adjustable antenna with adjustable electrical downtilt and azimuth. [technical background] [0002] The technology of mobile communication base station antennas has developed rapidly. Initially, ordinary directional and omnidirectional antennas were mainly used in China. At present, electronically adjustable antennas are becoming more and more popular. The so-called electronically adjustable antennas refer to base station antennas that can adjust the electronic downtilt angle. The principle of electronic downtilt is to change the phase of the collinear array antenna oscillator, change the amplitude of the vertical component and horizontal component, and change the field strength of the composite component, so that the vertical directivity diagram of the antenna is downtilted. Since the field strength in all direction...

Problems solved by technology

[0003] The above characteristics of the electric adjustable antenna determine that in order to realize the precise adjustment of the downtilt angle, it is necessary to ensure the ideal setting of the mechanical inclination angle of the antenna vibrator, otherwise the ideal pattern cannot be obtained only through the adjustment of the electric downtilt angle, which will affect the installation of the antenna. Construction puts forward very high requirements. Usually, it is very difficult to adjust the mechanical inclination angle of the antenna vibrator after the antenna is installed, and the error is large. Both construction and maintenance require high costs, and it is usually not ideal effect; on the other hand, the traditional electronically adjustable antenna can only adjust the electrical downtilt, but cannot adjust the azimuth in the horizontal direction, and it is usually adjusted manually, and the accuracy is very poor

In addition, the downtilt angle can only be adjusted within the range of the signal coverage sector. If it exceeds the range of the signal coverage sector, it can only be solved by adding a new antenna, which is very expensive. By adjusting the horizontal direction of the antenna oscillator Orientation can solve this problem very well
