The road traffic density is continuously increasing. By the intensive use of automobiles, it comes

to considerable difficulties and unpredictable events. The frequency of traffic obstructions, traffic

jams and accidents will also increase in future. A solution for this problem would be that

the driver would be supplied information when he is on the road. The information should be

including about road and traffic conditions and also information about other vehicles, which in

the near vicinity.

This kind of information sharing between vehicles is called C2C communication.Especially in

Europe there are many projects which are working for different C2C communcation applications,

like.

Objective of this thesis is based on former works, which optimized the antenna positions

for C2C communication by ray tracing simulation. The investigation of antennas for the C2C

communication, two different approches are taken in to account, a narrow band, and broad band.

Investigation of transparent material for broad band is also the part of this thesis.
