Abstract
To install, in or on a road surface of a road, a magnetic marker having retained in its outer perimeter an RFID tag including an antenna for wireless communication, an arrangement step of accommodating the magnetic marker in an accommodation hole provided to be bored in the road surface and a formation step of providing the magnetic marker with a protecting part for isolating the antenna from water are performed. With these steps, even if the periphery of the magnetic marker is submerged in water after installation, high communication performance of the RFID tag can be kept.
Claims8
A magnetic marker installation method for laying, in or on a road, a magnetic marker having retained therein a wireless tag including an antenna for transmitting or receiving electric waves for wireless communication, the installation method comprising:
- an arrangement step of arranging the magnetic marker in or on the road;
- and
- a formation step of providing the magnetic marker with a protecting part for isolating the antenna from water,
- wherein the antenna includes waveguide parts made of a conductive material and a gap formed by any two of the waveguide parts arranged to face each other, and
- the formation step is a step of providing the magnetic marker with the protecting part so that a distance for isolating the antenna from water is longer than the gap.
