Background
With the development of mobile communication, in order to provide higher quality network services, mobile communication service operators have proposed the concept of full coverage and seamless coverage, and the investment in network construction is continuously increased. The cell beautifying antenna plays an important role in seamless coverage as an important supplementary product for network coverage, but the horizontal main lobe width of the current product is a fixed value, and interference between adjacent cells is easily caused during coverage to influence the quality of coverage.
The width of a main lobe of a horizontal plane of the existing spot lamp antenna is not adjustable, so that the coverage area is small or the interference of adjacent cells is easily caused; in addition, in the existing scheme, the width or the side angle of the reflector plate of the reflector lamp antenna is adjusted to change the width of the main lobe of the horizontal plane, but the adjustment mode is that the size of a metal piece is changed, so that the deterioration of third-order intermodulation is easily caused, and the communication quality is influenced by the interference of uplink and downlink communication. Therefore, it is necessary to design a new product to meet the actual use requirement.
