Compact Eight-Band Monopole for LTE Mobile Phone

A compact eight-band monopole for LTE mobile phone is presented. The antenna is mainly composed of a Tshape monopole and a coupled parasitic ground strip which are excited to cover LTE800/GSM850/GSM900 bands. Moreover, three modes of parasitic ground strip contribute to covering the DCS/PCS/UMTS/LTE2300/LTE2500 bands. The merit of the proposed antenna is to cover eight bands in the 2G/3G/4G bands without any lumped-element matching circuit under the condition of $19\times 46\times0.8$ mm3 nonground portion, which is suitable for the wideband LTE mobile phone applications. Good agreement is achieved between the measurement and simulation results.
