Abstract:

This paper discussed literature review of different authors who tried different technique to improve the mutual coupling in UWB MIMO patch antenna. Ultra-wideband (UWB) systems have been received a growing interest due to the successful applications of high throughput, multimedia streaming, radar and biomedical imaging. Federal Communications Commission (FCC) has approved the use of the frequency range of 3.1–10.6 GHz without license for low power emitting systems. The UWB systems operate over a wide bandwidth with low spectral power level. The signal to noise ratio (SNR) is hence too low at the receiver. The throughputs of the systems have been also extremely increased thanks to the recent developed data coding techniques. However, it has been almost restricted, since the emitted signals are inherently subjected to interference and multipath fading in propagating environments. The transfer rate can be excessively increased and the fading effects can be reduced by utilizing multiple input multiple output (MIMO) concept because of introducing spatially multiplexing and diversity. Designing MIMO systems with multiple antenna elements for mobile terminals has been more difficult since the mobile terminals have been towards to be smaller, and thus MIMO antenna elements must be accommodated in these constricted terminals with the other electronic components. At the same time, the elements are inevitably exposed to high mutual coupling among them, because of operating closely each other. Mutual coupling must be minimized to isolate the channels electrically to provide an efficient MIMO system.
