This paper introduces a method of antenna parameter selection in LTE network planning

which can effectively improve the coverage of network. The method can calculate all parameters of the antenna according to the position relation of target base station and adjacent base stations

which can optimize the network structure. The paper makes a simulation of network planning in one city

which proves the feasibility and effectiveness of the method. The method proposed in this paper can save a lot of time and resources when used in planning and optimization of LTE network.
