Our residential area, we sometimes meet heavy snowfall and lose vehicle location by low visibility. In order to overcome such condition, we develop vehicle navigation system with UHF RF-ID. In our navigation system with RF-ID system, vehicle location data is set on RF-ID tags buried in the asphalt road. And a driver takes vehicle location data by RF-ID antenna of RF-ID system from RF-ID tags. In our driving experiment, we put bubble wrap on the windshield in front of driver's seat to make the low visible condition. In such condition, our navigate system contributes to keep driving lane. In our driving experiment, we use two types of antenna systems; 1 antenna system and 2 antennas system. In this paper, we will compare 1 antenna system with 2 antennas system.
