In this study, a dual band-notched ultra-wideband tapered slot antenna is introduced. Here, split ring resonator and balun are used to suppress spurious unwanted bands. The split ring resonator is etched to the certain distance from the excitation point. Hence, one resonance is excited with extended band width. According to the feeding configuration, the stepped microstrip line and slotline connected with circular slot. So, strong EM wave coupling is generated with balun. The electric-field-coupled (ELC) resonator structure is placed inside the circular balun. The size of the tapered slot antenna is 55×40 mm2. The simulation results show that the impedance bandwidth of the antenna is covered an ultra-wideband frequency range (3.1 to 11 GHz) with VSWR< 2 and the band rejection is created at WLAN and ITU band.
