Title:
CONVERTER METHOD IN ELECTRIC WAVE ENVIRONMENT, REFLECTION STRUCTURE BODY, AND ON-ROAD COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2001345631
Kind Code:
A
Abstract:
To obtain low-cost counter measures in electric wave environment for reflecting secondary reflection waves in a desired direction without affecting a system for applying primary reflection waves from a road surface to a reflection structure body.
A plurality of reflection plates having the angle of a reflection surface that is related by distance depending on positions between a road-side antenna and the reflection structure body, or the incidence angle of incidence waves to the reflection structure body are mounted on the reflection structure body.
