Performance Evaluation of a Substrate Integrated Waveguide Antenna for Vehicular Networks

This paper describes the design and evaluation of a Substrate Integrated Waveguide (SIW) antenna operating at 2.4 GHz. This antenna was designed as a possible solution for the implementation of the vehicular networks (VANETs). The main advantages of the SIW antennas, such as their simplicity, small size and low cost, make this kind of antennas particularly suitable for using in wireless nodes where the size is a critical factor. For example, in Vehicular Networks (VANETs) which is one of the most promising wireless communication systems. We present in this paper the design of the SIW antenna using the software ANSYS HFSS as well as the results of the assessment of some parameters like the radiation pattern, operation frequency and bandwidth. Also, we present the simulation of a VANET that include the designed parameters of the SIW antenna in order to evaluate its integration into the vehicular nodes. This simulation was performed in the NS2 simulator and some network performance metrics, like packet delay and the packet loss rate, were evaluated. Other additional software, for example MOVE and SUMO, were also used to generate the routes and the movement of the vehicles
