Microstrip-fed quasi-Yagi antenna array for a different DSRC system

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 cable to an antenna located under the lane structure. The antenna had been simulated using CST Microwave Studio software. The antenna was fabricated on Rogers RO4003 substrate. The proposed antenna profile provides at 5.8 GHz: a measured return-loss of -16 dB and a high simulated gain of 16.75 dB.
