RFID technology for vehicle and container tracking
Challenges:
- Extremely lossy environment due to the presence of numerous metals that cause degradation in wireless signals
- Operating bandwidth of RFID nodes can vary from one country to another
- Multipath effect of wireless signals
- Power Constraints
- Materials (substrate for electronics) and packaging
RFID in Automotive Applications
Example: Radiation for a single car
RFID Tag placed vertically on the license plate
Example: In the Parking Lot
Shows the importance of placing the RFID tag correctly.
Radiation Pattern of RFID Antenna placed on the back car's license plate
Model of car body in 3D EM Simulator FEKO
The existence of the front car heavily suppresses the signal of the RFID placed on the back car’s license plate. Energy goes from the back instead of front. It shows the importance of looking for the correct place for RFID tag.

Environmental Factors
Snow, Ice, Rain, Humidity
- May build a thin/thick layer of ice/snow/water on windows
- Simulate the environment with the humid conditions (changes in dielectric constant and loss tangent of air)

Tire Analysis
Tilt the antenna 45°
Radiation normal to the tire is better
