摘要：
A design of MIMO antenna with four elements each one consists of two polarized ports is proposed in this research. The design of each elements based on ZORA which is applied to get the advantage of band frequency flexibility. The proposed MIMO antenna is operated as a single and dual band by adjusting a ground structure. The resonance frequency is 3.9 GHz for single band with bandwidth 1 GHz (3.4-4.4) GHz at -10 dB with -27 dB isolation. The resonance frequencies for dual band are 4.95 and 7 GHz with bandwidth 1.23 GHz (4.03-5.26) GHz and 410 MHz (6.88-7.29) GHz at -10 dB and less than -12 dB isolation for both bands. The obtained size of FR-4 PCB for single band is 77 × 150 mm2 while 82 × 150 mm2 for dual band which are suitable for future smartphone. © 2021 Budapest University of Technology and Economics.
