FOUR-ELEMENT MIMO ANTENNA WITH HIGH ISOLATION AND DIVERSITY PERFORMANCE FOR UWB APPLICATIONS
SINOPSIS
A four-element multiple-input multiple-output (MIMO) antenna for wireless ultra-wideband (UWB) applications is proposed in this study. The single-element antenna is derived by conducting several design evolutions. This fundamental antenna achieves an UWB impedance bandwidth with good positive gain across the operating frequency ranges. In the investigation of MIMO antennas, dual and four-element MIMO antennas with variable layouts are designed and analyzed according to their S parameters, gain, radiation pattern, and diversity performance findings. Thus, a four-element MIMO antenna operating in the frequency range of 3.5-11.2 GHz with > -20 dB isolation in the majority of the band is proposed. The diversity performances in terms of envelope correlation coefficient and diversity gain are less than 0.006 and greater than 9.9, respectively, while the mean effective gain (MEG) and channel capacity loss (CCL) are within acceptable ranges. The simulated findings agree well with the measured results.
