Abstract
In order to prevent the interference problem due to existing nearby communication systems within the UWB operating frequency, a synthesis design of single band-notched UWB antenna using the Complementary Split Ring Resonator CSRR is presented. A novel technique to obtain the notch function is proposed and analyzed, using the CSRR dynamic resonance frequency. This technique offers good filtering properties in term of rejection level and stopband bandwidth, compared to the conventional method implementing the CSRR quasi-static resonance. However it is depending on the appearance of the first and the third resonances in the UWB response. Two UWB antenna prototypes with single notch frequency centered at 5.5 GHz are fabricated and measured to validate the study presented and good agreement is achieved between measurement and simulation.
