Antenna characteristics and ranging robustness with double quadrature receiver and UWB impulse radio

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.
