      Abstract: In order to make the miniaturized base station antenna array to adjust the coverage, the base station antenna array needs to have the function of electrical downtilt. In this talk, we briefly describe the research advances of the elements and arrays of base antennas in recent years. Secondly, the design principle and performance parameters of the base station antenna and phase shifter are elaborated. Then, three different shapes of sidewalls are proposed on the reflector plate of the six-element antenna array to improve the radiation performance of the antenna array, and a one-five-structure longitudinal sliding phase shifter is designed. Finally, the designed antenna array and phase shifter are physically processed and combined, and the miniaturized broadband dual-polarized base station antenna array is obtained. Its operating frequency band is from 1.71 GHz to 2.69 GHz with an adequate downtilt angle range (0 ° ~ 10 °).
