Experimental study of ultra wideband antenna performance with laptop computers

The experimental study of the ultra wideband (UWB) antenna performance with laptop computers in an indoor channel are analyzed at 3.1 GHz to 10.6 GHz frequency band. The characteristics of indoor propagation channel are very complicated and difficult to predict. Therefore, the performances of UWB antenna signal shall be considered. This paper present the UWB antenna performance. The rectangular passband waveform, which satisfied the Federal Communication Commission (FCC) definition of UWB signal and FCC spectral masks for the indoor limits, are considered. In addition, we considered the matched filter for the receiver side to maximize the signal to noise ratio (SNR). The UWB antenna transfer function, the UWB signal waveform of the UWB systems are evaluated. The transmission gain, the correlation coefficient are presented and discussed.
