Abstract

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| (ij, 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.
