摘　　要：提出了一种l紧凑型具有阻带特性的平面超宽带天线，天线采用共面波导馈电，由不规则五边形辐射单元和L形地板印制在FR4介质板同一表面构成。天线工作在3．1-10．6GHz频段，通过在辐射单元上添加C形缝改变电流分布实现中心频率为5．5GHz阻带特性，阻带频段的中心频率和阻带带宽分别取决于C形槽的角度和C形槽宽度。仿真和测试数据证明文中所提出的的天线能胜任UBW应用并具有有效的阻带特性。In this article, a compact stop-band ultra-wideband antenna has been designed. The proposed antenna consists of a irregular pentagon radiating element and two L-shaped ground planes with coplanar waveguide feed. It is printed on the same side of a low-cost 32 ＊26 ＊ 1.6mm FR4 substrate with permittivity of 4.4. By inserting a C- shape slot in the radiation patch, a stop-band generates at 5.1 ＊ 5.9 GHz. The center frequency of the stop-band depends on the angle of the C shape and the bandwidth depends on the c-shaped slot width. The simulated and measured results, including voltage stand wave ratio, radiation pattern, and gain, match well. The results demonstrate that the proposed antenna is not only suitable for uhra-wideband applications but also for 4G long-term evolution applications.
