摘要 提出了一种具有双阻带特性的共面波导馈电超宽带天线。通过在辐射单元上开E型槽实现了3.75 GHz的第一个陷波结构,并在地板上开两条对称槽实现5.5 GHz的第二个陷波结构。文中提出的具有阻带特性超宽带天线的实测结果与仿真结果吻合较好。除了两个期望的阻带外其他超宽带频段内,该天线满足VSWR<2。同时给出了仿真辐射方向图和增益图。 A copolanar waveguide（CPW） fed ultra-wideband antenna with the dual band-notched characteristic is proposed.An E-shape slot is etched from the radiator to achieve a notched band at 3.75 GHz,and the other notched band at 5.5 GHz is obtained by etching two symmetrical slots from the ground plane.Good agreement between measurement data and simulation results is obtained.The voltage-standing wave ratios（VSWR） are all less than 2 in the UWB band except in the desired notched bands.The simulated radiation patterns as well as gains of the proposed antenna are also presented.
