Multiband handset antenna analysis including LTE band MIMO service

Abstract

A compact multiband handset antenna including MIMO antenna operation for LTE 13 band (746 ~ 787 MHz) applications is proposed. The proposed antennas are separately located on the top and bottom portions of a mobile handset in order to use the antenna area more effectively. The proposed antenna achieves isolations of higher than 14 dB, enveloped correlation coefficients (ECC) of less than 0.25, and total efficiencies of greater than 40%. The operating frequency bands of Antenna 1 and Antenna 2 include the LTE 13 (746 ~ 787 MHz)/DCS/PCS/UMTS (1710 ~ 2170 MHz) bands and the LTE 13 (746 ~ 787 MHz)/GSM850/900 (824 ~ 960 MHz) bands, respectively.
