Effect of Circular Split Ring Resonator Array on Circular Microstrip Antenna Used for Intelligent Transportation System (ITS)

In this paper, Split Ring Resonator (SRR) array are loaded in substrate of a circular microstrip antenna used for intelligent transportation system (ITS). The operating frequency of this antenna is 5.9 GHz for ITS band. Dual band operation is also observed when the array of SRR designed whithin substrate for the RLAN application [5.47 – 5.725]. Thissimulation works had been done in CST Microwave Studio simulation software. The parameters that considered are return loss, bandwidth, resonant frequency, radiation pattern and gain.
