Abstract

In order to ensure the timeliness of communication avoiding communication blind area, to solve the communication problem of the same mobile phone in different frequency bands, based on the planar monopole antenna structure, the dual-band mobile phone antenna can be used in the TD-SCDMA (2.0102.025GHz) and TD-LTE (2.575–2.635GHz) frequency band has been proposed in this paper. And, the dual-band phone antenna has been modeled, simulated and optimized by using the Ansoft HFSS software. The simulation results show that the performance indicators of the dual-band mobile phone antenna such as return loss of the antenna, antenna gain, voltage standing wave ratio (VSWR), impedance matching, etc. working in the two frequency range of TD-SCDMA and TD-LTE can meet the data demand of the mobile terminal demand, and it has good practical value.
