A compact broadband MIMO antenna for mobile handset applications

A compact planar broadband multiple-input multiple-output (MIMO) antenna, which has a good performance under MIMO situations with low mutual coupling (<−11 dB) and low correlation coefficient (≤−15 dB) is presented. The antenna operates a very wide band with good impedance matching (S₁₁ <−10 dB), covering the LTE band 33–37 and 39–40. The elements are mounted on the same side of ground plane with the inter-element space of 32 mm. The total size of the array is compact (50 mm × 67.2 mm × 0.254 mm), suitable for mobile handset applications. © 2011 Wiley Periodicals, Inc.
