SRRs effect on circular antenna with elliptical rings for ultra-wide-band

This paper presents a novel microstrip antenna that consists of conducting circular patch with elliptical etched rings and partial conducting ground plane. The fabrication was done using Rogers 5880 LZ substrate, and the dimensions are selected to be 45mm × 31mm × 1.27 mm. Split Ring Resonators (SRRs) will be used to enhance gain performance for wide frequency band. The Split Ring Resonator design is simulated using HFSS (High Frequency Structure Simulator). The final antenna simulation results along with the SRR group delay, maximum antenna gain, radiation pattern, S11 and VSWR are illustrated. The presented antenna achieved the desired BW and the simulated S11 and VSWR are coherent, showing a unique performance.
