In this paper, the proposed study is based on the development of an antenna reader RSE according to the European DSRC Standards. A microstrip antenna array was designed using multiple superstrate layers, to overcome the disadvantage of low gain of a simple microstrip antenna. The DSRC preconditions have a large impact on the antenna design; the RSE antenna gain pattern must be reasonably wide in order...
In this paper an integrated Microstrip-fed quasi-Yagi antenna array for a different DSRC system is proposed. In classical DSRC Free-Flow, the antennas are placed in areas visible to the driver: aerial platforms on highway lanes, boxes next to the highway, etc. In this proposed DSRC system, based on the European DSRC standards, the identification is performed by a reader connected via buried coaxial...
