Problems solved by technology
[0005] At present, there are two ways to change the phase of the output signal of the base station antenna, using RCU electric adjustment or directly manually adjusting the phase shifter. If it is a base station antenna with manual adjustment (without built-in RCU), special tools are required to adjust the downtilt angle. To remotely adjust the downtilt angle, an external RCU connection must be used; if the base station antenna has a built-in RCU, the downtilt angle of the antenna cannot be adjusted manually. When the RCU is damaged, the downtilt angle of the base station antenna can only be adjusted after the RCU is replaced. adjust

The invention provides an antenna electronic downward inclination angle adjusting assembly and an adjusting method thereof, and the antenna electronic downward inclination angle adjusting assembly comprises an angle scale which passes through a first channel of a first buckle from a first side; the transmission ruler is arranged below the angle ruler in parallel and penetrates through the second channel of the second buckle from a second side opposite to the first side; the two ends of the sliding block are connected with the first buckle and the second buckle through connecting rods respectively, the transmission ruler, the sliding block and the two connecting rods jointly form a trapezoidal frame, when the angle ruler is pulled, the trapezoidal frame is compressed in the direction perpendicular to the movable ruler, the sliding block ascends to abut against the transmission ruler, and therefore the transmission ruler is linked by the angle ruler to move in the same direction. According to the invention, remote electric adjustment and manual adjustment of the downward inclination angle of the antenna can be realized, a special adjustment tool is not needed during manual adjustment, and the speed is higher during manual adjustment.
Description
technical field [0001] The invention relates to the field of communication equipment, in particular to an antenna electronic downtilt adjustment component and an adjustment method thereof. Background technique [0002] The coverage of the antenna is achieved through the vertical main beam, and the adjustment of the downtilt angle changes the coverage of the main beam. For the electrically adjustable antenna, the phase shifter is used to change the phase of the power signal obtained by each radiating element (vibrator) in the antenna array to realize the downtilt of the main beam in the vertical plane. It is the application of radar phased array technology in mobile communication. 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 antenna The vertical direction graph of is tilted dow...
