Measurement characteristics of LTE-MIMO antenna for 4 G mobile handy terminal

This paper presents measurement characteristics of LTE-MIMO antenna for 4 G mobile handy terminal. The considered LTE band is the class 13 and 14 in this research. Main antenna is operated reconfigurable by voltage control. The measured bandwidth of proposed antenna has been observed about 53 MHz (746~798 MHz) for VSWR 3:1. The measured isolation between main antenna and sub antenna has been showed about - 13 dB below at LTE band.
