Abstract :
This paper presents design of a novel compact UWB antipodal Vivaldi antenna, where band-notch characteristics within 5-6 GHz frequency range is achieved by placing a parasitic rectangular SRR near the radiating arm, in order to reduce electromagnetic interference with IEEE 802.11a and HIPERLAN/2 systems. Simulation results show that the proposed antenna provides wide impedance band-width with satisfactory rejection in the desired band along with good gain and stable radiation pattern in the rest of the UWB regime.
