Multiple Antennas Effect on UWB Rake Receiver Performance
In this paper, the authors discuss the enhancement of the proposed UWB antenna design that can be used in wireless UWB systems. The small antenna design was simulated by CST software to present the performance of the main antenna parameters. The return loss is less than -10 dB from 3.5 GHz to 10.8 GHz which is covering the UWB bandwidth. This antenna was applied in Multiple-Input Multiple-Output (MIMO) scheme in indoor transmission/reception system to improve the propagation bit rate or to increase the channel capacity.
