Abstract:
A dedicated short-range communication on-vehicle apparatus easily attachable on a wind shield of the motor vehicle includes an antenna, a radio module, a data processing unit and others contained in a single box-like housing. The antenna ( 8 ) has directivity in a predetermined orientation. The radio module ( 10 ) performs transmission/reception of radio wave with road-side radio equipment through the antenna ( 8 ). The data processing unit ( 11 ) processes data transferred through the radio module ( 10 ). The box-like housing ( 4 ) houses the antenna ( 8 ), the radio module ( 10 ) and the data processing unit ( 11 ) en bloc. The box-like housing ( 4 ) is fixedly attached onto a windshield ( 3 ) of the motor vehicle at a mounting plate ( 4 a) of the housing ( 4 ) on the antenna radiation side by an adhesive member ( 30 ). A radio wave aperture portion of the mounting plate ( 4 a) is made of a radio wave transmissible material.
