UWB sensor network on 2-D waveguide sheet

Abstract

In this paper we propose a room-size ultra-wideband (UWB) wireless communication system for fast data transmission of sensor networks. We use two-dimensional signal transmission (2DST) for wireless communication. In the proposed system, planar waveguide sheet is used as a medium guiding microwave and receiver couplers on the sheet extract microwave across the sheet surface. We design the UWB coupler and demonstrate the validity by numerical simulation. Experimental results show that the fabricated couplers can mediate sufficient power for UWB communication.
