On the integration of ultra wideband antennas in DVD players

Impulse radio (IR) ultra wideband (UWB) is one of the possible wireless technologies to develop indoor high data rate communication systems. Due to their high bandwidth, UWB antennas introduce distortion influenced by the device where they are integrated, decreasing the system performance in terms of bit error rate (BER). The goal of this paper is to provide a method to evaluate the best location of an antenna near a consumer device, and particularly a DVD player. The proposed method analyses the most important factors that maximize the BER by means of an electromagnetic vision study (EVS) and a fidelity analysis. These quantitative evaluations identify the best position of the antenna in terms of power and distortion.
