Description

Technical field

[0001] The invention relates to a detection device for the electric downtilt angle of the electric adjustment antenna of a mobile communication base station, and also relates to a detection method using the detection device for the electric downtilt angle of the communication antenna. Background technique

[0002] Plate-shaped base station antennas are widely used in the field of mobile communications, and the downtilt angle of the antenna determines the coverage area that the antenna beam points to. Antennas that use mechanical angle adjustment or fixed electrical downtilt have been difficult to meet the requirements of network optimization. The electronically adjustable antenna is very suitable for solving the problem of cross-area interference caused by dense users and small station distance in large and medium-sized cities, and it is very convenient to solve the problem of temporary traffic hotspots that often appear in urban areas. In communication netw...
