A MIMO ANTENNA ARRAY WITH HIGH GAIN AND LOW MUTUAL COUPLING FOR WLAN APPLICATION
Using MIMO antennas is necessary in tranceivers in order to improve the data rate in wireless systems. The paper proposed a MIMO antenna array consisting of sixteen microstrip elements in four arrays with four ports. The antenna array operates at a center frequency of 5 GHz with a bandwidth of 331 MHz. The muture coupling between antenna elements is low due to flector integration, with |Sij| (ij, i, j = 1-4) less than-31 dB over the operating band. The antenna is designed on the RO5880 substrate and simulated by CST studio software. The MIMO antenna size is 140×134×45mm which can be suitable for stations in Indoor Positioning Systems, transceivers operating around 5 GHz for long distances, as well as Wi-Fi 802.1j.
