This paper presents the design, fabrication and characterization of circular ring monopole antenna (CRMA) for dedicated short range communication. Design simulation is carried out with the aid of Attar FEKO (2017) Solver The 26×20×1.6 mm antenna was fabricated using an FR4 composite material. The return loss of prototype is measured with Anritsu MS 2036C Network Analyzer. Between the measurement and simulation result is a little different but two results cover DSRC band. The return loss is about -37 dB and fractional bandwidth of 26.9 % at the selected frequency 5.9GHz. The antenna provides input impedance bandwidth of 1.59 GHz (4.7 to 6.36 GHz) which fully covers 5.875 to 5.925 DSRC bands. It can realize near omnidirectional radiation pattern in the H- plane and linear polarization antenna due to the phase changing of current distribution. In this research work, circular ring monopole antenna is small in size, simple in design and fabrication but its performance is the best for DSRC applications.
