Radio Link Characterization using Real Antenna Integration Scenarios for UWB Consumer Electronic Applications

The radio link performance of short range but high data rate UWB systems is affected by both the antennas and the channel. Both aspects have been widely investigated in related literature. With respect to the antenna it is often the goal to minimize the ringing to affect less the impulse radiation. Unfortunately, in most studies the antenna integration into the chassis of the specific application is not taken into account. Investigations in this paper show that the integration significantly affects e.g. the ringing of the antenna. In order to investigate the impact of this degradation on the radio link between different applications like DVD player and PDA in a typical indoor environment propagation modeling is performed. The results show that the delay spread of the channel dominates the performance of the entire radio link. The increased ringing due to the antenna integration adds only minor to the overall performance.
