Planar Monopole UWB Antenna Loaded with SRRs and ESSRR for Triple Band-Notch Functions

A triple band-notched ultrawideband (UWB) trapezoidal shape microstrip-fed patch antenna on FR4 substrate is proposed. Notch stop bands are achieved around the WLAN (5.15-5.25 GHz), WiMAX (3.3-3.8GHz) and X-band (7.9-8.4 GHz) by etching one elliptic single split-ring resonator (ESSRR) from radiating patch and by placing two squaresingle split-ring resonators(SSSRRs) of different dimensions near feedline, respectively. Results are experimentally demonstrated over the UWB operation.
