Design and simulation of a microstrip patch antenna for 5.9 GHz Dedicated Short Range Communication system (DSRC) is presented in this paper. DSRC is a wireless communication technology which has been developed for the enhancement of safety of the transport system. It operates at 5.9 GHz band (5.85-5.925 GHz). It provides 75 MHz of bandwidth. The designed antenna shows good return loss of -17.5 dB at 5.9 GHz and provides a gain of 8 dBi. The simulation is performed using SEMCAD X electromagnetic simulation tool. The proposed antenna is suitable for DSRC applications.
