Abstract

This paper analyzes the effect of the antenna characteristics on the ranging precision of UWB impulse radio receivers. It shows that the influence of the antenna highly depends on the chosen RF architecture. The single quadrature receiver architecture is first explained and analyzed. Then the double quadrature receiver is presented and its robustness is justified. A small size miniaturized ultra wideband antenna is then described. This antenna is exploited to validate the robustness thanks to link level simulations.
双正交接收机和超宽带脉冲无线电的天线特性和测距鲁棒性
分析了天线特性对超宽带脉冲无线电接收机测距精度的影响。结果表明,天线的影响很大程度上取决于所选择的射频结构。首先对单正交接收机结构进行了解释和分析。然后提出了双正交接收机,并对其鲁棒性进行了验证。然后描述了一种小尺寸小型化的超宽带天线。通过链路级仿真验证了该天线的鲁棒性。
