Abstract

The invention provides an antenna and an adjusting device for the electrical downtilt of the antenna. The adjusting device comprises an electric tuning unit, a first transmission mechanism, a pull rod, a second transmission mechanism, a potentiometer and a phase shifter, wherein the first transmission mechanism is respectively and mechanically connected with the electric tuning unit and the pull rod for converting rotary movement output by the electric tuning unit into linear movement of the pull rod, the second transmission mechanism is respectively and mechanically connected with the pull rod and the phase shifter for transmitting the linear movement of the pull rod to the phase shifter, the potentiometer is directly and mechanically connected with the pull rod, and is also electrically connected with the electric tuning unit for enabling the electric tuning unit to receive a resistance value measured by the potentiometer and to adjust the rotating angle of the electric tuning unit according to the relationship between the resistance value and the electrical downtilt of the antenna. Through the above manner, adjustment for the electrical downtilt of the antenna can be realized by the adjusting device with a simpler structure, the cost is relatively low, the transmission error during adjustment can be reduced, and the adjusting precision of the electrical downtilt of the antenna is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna and an adjustment device for an electric downtilt angle thereof. Background technique [0002] Various types of communication antennas such as base station antennas usually need to be tilted downward relative to the horizontal line at a certain angle during operation. This angle is called the antenna downtilt or depression angle. By adjusting the downtilt angle, the radiation effect of the antenna can be directly affected, that is, the coverage. At present, there are mainly two ways to adjust the downtilt angle of the antenna, the mechanical downtilt angle and the electric downtilt angle. Among them, the electric downtilt angle can be controlled by remote electric adjustment, and the cost is low, so it is more and more widely used. [0003] An electric downtilt adjustment device in the prior art includes a phase shifter for moving the downtilt angle of the antenn...
