High gain microstrip patch antenna array using multiple superstrate layers for DSRC applications

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 to get a long enough communication time while passing an OBU with high speed and to allow the system to be operational in rain, snow or frost.
