Summary:Packet relay-assisted scheme using sectorized receiving at relay station has been proved as an effective solution to mitigate hidden terminal problem, and then improve performance of ITS V2V communication. In addition, it is also shown that performance of the relay-assisted scheme relies on separation of the sector antenna unit which is basically expressed as front-to-back (F/B) and front-to-side (F/S) ratios. In this paper, a sectorized antenna is designed and the actual separation is measured under multipath environment. The results show that actual F/B and F/S separations are 7~18 dB lower than the designed values. Based on the results, some suggestions to improve the separation are presented.
