为了减小对IEEE 802.11a和HIPERLAN/2系统的电磁干扰，设计了一种新型超宽带（UWB）对跖Vivaldi天线，通过在天线辐射臂附近放置一个寄生矩形SRR来实现5-6 GHz频率范围内的带陷特性。仿真结果表明，该天线具有较宽的阻抗带宽，在所需频段沿着具有良好的抑制性能，在其余频段具有良好的增益和稳定的辐射方向图。
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.
