Body-effect-adaptive Compact Wideband LTE MIMO Antenna Array with Quad Elements for Mobile Terminals

摘要

A body-effect-adaptive compact wideband LTE MIMO antenna array with quad elements for mobile terminals is proposed in this paper. It can cover the bands of 750-960 and 1700-2700 MHz with a low envelope correlation coefficient. Through different combinations two of the four elements can be utilized as dual element LTE MIMO antenna array to reduce three kinds of body effects (head and hand; single hand; dual hands) with the other two ports open. Some common rules about the body effects are introduced. The conclusions about the optimal chassis locations of LTE MIMO antenna elements to improve MIMO performance are also presented.
