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.
