With the acceleration of urbanization in China, the number of high-rise buildings has increased dramatically, and high-rise

residential areas depth coverage (more than 25 layers) is still a difficult point in 4G network construction. The conventional spotlight antenna of which the horizontal half-power beam width is 65 degree cannot solve the high and low layer coverage requirements very well. Aiming at this problem, a wide-angle spotlight antenna with a horizontal beam width about 25 degrees and a vertical beam width about 65 degrees can effectively improve the signal strength and coverage at high and low levels. This paper summarizes the applicable scene and antenna configuration principle of large-angle spotlight antenna by analyzing and testing the coverage effect of large-angle spotlight antenna on the residential areas. Different construction schemes are formulated for different building heights, width and spacing to provide reference for the design of deep coverage in high-rise residential areas.
