Test Equipment for Automotive Antenna

Test Equipment for Automotive Antenna

To measure the antenna quality, we need to test with RF modules with Automotive itself. Since Car drive in Downtown and suburb, it is required the test environment for the both simulation field.

Normally, we have evaluated Antenna quality of RF devices like a mobile phone under the Wave chamber room with absorbing wall and Anechoic Chamber with reflectors. Echo chamber emulate the environment of RIMP (Rich Isotropic Multi-Path) and is suitable of in-room and downtown situation with much scattered. On the other hand, in case of the environment of pure LOS (Line of Sight), its test should be in Anechoic chamber to test the fixed antenna.

In case of Suburb and highway driving situation, the environment is much similar to RIPM not LOS against the car on the road. It is RIMP and Romdom LOS that the two type of opposite environment for CAR radio communication system.
