An Eight-port MIMO Antenna for Mobile Handsets

Abstract

In this work, an eight-port MIMO antenna system for mobile handsets is proposed at 2.4 GHz. All the antennas are built from the frames of the handset, without adding any additional structure. The ground clearance is 2mm along all the peripheries. Among the eight antennas, four antennas rely on the higher order modes of the chassis to radiate, and the other four antennas are formed by the slots between the chassis and the frame. The isolation between the ports are above 10dB, and the envelope correlation coefficients are below 0.07 over the operating band, indicating good MIMO performances.
