Traditional antenna design fulfilled the base requirement of the mobile network.But considering the development of mobile network

the data throughput would be explosively increased.For improving the competence of our TD-LTE network

we are facing a lot of challenges from the design and development of the antenna to realize the optimal network performance（e.g.improving the network throughput） through the cooperation between the antenna and the network.From the network performance point of view

this paper gives the optimal antenna HBW by network planning and simulation under the environment of dense urban

urban

suburban and country.
