摘要

Low spatial correlation will increase the capacity of MIMO systems. In the MIMO antenna design, a low spatial correlation needs to be considered in supporting the maximum capacity. In this paper an 8 elements MIMO antenna was proposed and investigated for multiuser MMO router with 5 GHz frequency operation. Printed Yagi is used as an antenna element of the proposed MIMO antenna. In order to achieve low spatial correlation, cross-polarization arrangement between adjacent elements in proposed MIMO antenna is investigated to minimize coupling level. Numerical investigation has been conducted. The results show that the proposed antenna has cover large bandwidth around 5 GHz, from 4.54 GHz to 5.51 GHz with low return loss at 5 GHz. The cross polarization scenario successfully reduces the coupling level and produces the highest coupling level is -37 dB.
