A multi-band antenna, which consists of a diversity antenna in the DCS/PCS/UMTS bands and a MIMO antenna in the LTE17/LTE4 bands, is proposed and designed for mobile handset applications. The proposed antenna consists of the meandered PIFAs with branch lines. The radiation efficiency of the proposed antenna is higher than 30% in the LTE17/LTE4 bands and higher than 40% in the DCS/PCS/UMTS bands. The ECC between two identical antennas is less than 0.5 over the entire LTE17/LTE4/DCS/PCS/ UMTS bands.
