Abstract

3×3 Split Ring resonators with inner ring rotation are etched at the back side of Circular microstrip antenna with elliptical rings. Rotation for multiple angles leads to an enhancement in impedance bandwidth. The selected UWB antenna has fabrication dimensions of 45 mm × 31mm × 1.27 mm. The rotation of the inner rings occur clockwise and counter clockwise for -47°, 33° and 10°. The preferable enhanced frequency bandwidth is between 2.2 GHz and 9.8 GHz with return loss up to -23.16 dB at 3.8 GHz. S11, VSWR, maximum gain and group delay are obtained for the new design of the antenna via HFSS. This method of rotating inner or outer rings of SRRs will have massive researches in the near future.
