Abstract
The road vehicle communication system constitutes an important component of an intelligent transportation system (ITS). In this structure, control station is connected to base station via optical fiber for accomplishing high bandwidth data exchange. Due to millimeter-wave feature, the system has small cells and also provides high mobility. In order to have fast handover and dynamic bandwidth allocation, a medium access control scheme is used. Base stations are deployed along the road to support the communication link to a vehicle. In this paper, we use a quasi-crystal lens to focus the reflected waves to reduce the number of the base stations. The structure of the quasicrystal lens posses 12-fold symmetry and hence 12-fold symmetric quasi-crystal. In this quasi structure, we have demonstrated that if we select a proper slab thickness, we can achieve focusing in the outside of the slab as well as equal intensity of the source wave.
