Abstract
This thesis presents MIMO (Multiple-Input Multiple-Output) antennas designed for Ultra Wide-Band. The antenna system includes a Vivaldi antenna and a rectangular aperture antenna.
Polarization diversity and pattern diversity are employed in this design. Antenna bandwidth covers from 3.1GHz to 10.6GHz. Antenna gain is larger than 2dB.
In order to avoid the interference with wireless local area network (WLAN) of IEEE 802.a in the 5150–5825 MHz band, several frequency notch designs are included. The simulated and measured data are included with comparison. Some important parameters are simulated to verify MIMO performance. Correlation of the two antennas is below 0.1 and the diversity gain is greater than 4dB.
