To reduce the cost and increase reliability of the vehicle radio-frequency identification and tracking systems, an alternative placement of the interrogator is investigated. Conventional systems make use of an overhead interrogator that reads a tag in a windscreen or a license plate. The alternative approach is to embed the interrogator in the road and exclusively read license plate tags. In this...
A novel slot antenna designed on the road surface for machine-to-machine (M2M) RFID communication is presented. A corrugated ground plane with perturbed surface impedance is used underneath the antenna's radiator to adjust the antenna's radiation pattern, which otherwise will be highly affected by the properties of the road surface. The proposed antenna configuration is verified by full-wave simulations...
The main focus of this work is the functional verification of radio frequency systems on chip (RF SoCs). Different modeling approaches, like baseband modeling, analog modeling and event driven modeling, and their applications for verification are discussed. The possibilities and problems to use the Hierarchy Editor (HED) to switch between different modeling approaches on the fly in the top level schematic...
