Abstract
Communication between moving vehicles is very important for safety. In this paper, a bidirectional antenna that can be installed inside a vehicle is proposed and tested in a real vehicular environment at 5.8 GHz. The forward link and backward link seated by two persons and three persons were compared in terms of received RF power and the peak-to-average power ratio (PAR). It was found that, even with three persons, the power link fulfilled the communication requirements using the proposed antenna.
Highlights
Road traffic is becoming heavier, so that intelligent communication between moving vehicles is very important [1]
Vehicle-to-vehicle (V2V) communication for IEEE 802.11p Wireless Access in Vehicular Environments (WAVE) has been achieved by antennas installed on the roofs of vehicles [2,3,4]
Forward and backward links are compared, and the backward link seated by two persons and three persons is described
Summary
Road traffic is becoming heavier, so that intelligent communication between moving vehicles is very important [1]. Vehicle-to-vehicle (V2V) communication for IEEE 802.11p Wireless Access in Vehicular Environments (WAVE) has been achieved by antennas installed on the roofs of vehicles [2,3,4]. Installation of the antenna should cut part of the roof of the vehicle. An antenna that can be installed inside a vehicle is proposed for WAVE communication operating at 5.8 GHz. Experiments on a power link between two vehicles are done. Forward and backward links are compared, and the backward link seated by two persons and three persons is described
