Abstract
In this article, a dual-band multiple input multiple output (MIMO) antenna is proposed for Mobile WiMAX applications.The designed MIMO antenna consists of two planar inverted F antennas (PIFAs) and two isolators. The PIFAs have a volume of 12 × 10 × 4 mm3, which is small enough to be incorporated in a mobile MIMO terminal. The two isolators are designed symmetrically and placed between the two PIFAs to enhance the isolation performance of the MIMO antenna by suppressing the current flow between the antennas in the 2.3 and 3.4 GHz bands. The measured isolation values (S21) are lower than −15 and −22 dB at the 2.3 and 3.4 GHz bands, respectively. The key design parameters are extracted, and the parametric analysis performed. Also, the overall performance of the optimized MIMO antenna is presented. © 2010 Wiley Periodicals, Inc.
