Compact multiband MIMO antenna designs and analysis for 2.4/5.2/5.8 GHz WLAN MIMO systems

In this study, high gain, low noise MIMO antenna system have been analyzed and designed in wireless ISM band communication system. An isolation technique for two small-size WLAN MIMO laptop computer antennas covering the 2.4/5.2/5.8 GHz bands is presented. The aim of this project is to present several types of compact MIMO antennas for ISM 2.4 and 5.8 GHz band, and then to compare and interpret the results. Besides, some information was provided as to the ISM band and transceiver systems. Also, the correlation coefficient and diversity gain, which represents a significant value for MIMO antennas, has been analysed in this paper. The different geometries of microstrip antennas such as slot-loaded microstrip patch arrays, dual-band and loaded dipole rectangular microstrip patch are simulated with CST Software, using FDTD.
