摘　　要：为了获得更小的天线尺寸和稳定的辐射模式,提出了一种共面波导(CPW)馈电的三维小型化圆形超宽带(UWB)天线。在圆形平面UWB单极子天线的基础上,通过在圆形辐射贴片和接地面上垂直加载金属翼的方式,实现了同时工作于无线局域网(WLAN)和UWB应用频段的小型化UWB天线设计。利用电磁仿真软件对天线性能进行了仿真。仿真结果表明:在2.39~10.76 GHz频段内,该天线反射系数小于-10 dB,峰值增益为1.3~4.6 dB,辐射效率大于80%,群延迟小于0.5 ns,面积为24 mm×29 mm。相对于传统的圆形平面UWB单极子天线,该天线尺寸减小了44%,在小型化无线通信设备中具有广阔的应用前景。In order to obtain smaller antenna size and stable radiation pattern,a co-planar waveguide(CPW)three-dimensional compact circular ultra-wideband(UWB)antenna is proposed.On the basis of circular planar UWB monopole antenna,a miniaturized UWB antenna for both WLAN and UWB applications is designed by vertically loading metal wings on the circular radiating patch and the ground plane.The performance of antenna is simulated by electromagnetic simulation software.Simulated results show that:in the band of 2.39~10.76 GHz,the reflection coefficient of the antenna is less than-10 dB,the peak gain is 1.3~4.6 dB,the radiation efficiency is more than 80%,the group delay is less than 0.5 ns,the area of the antenna is 24 mm×29 mm.Compared with the traditional circular planar UWB monopole antenna,the size of the antenna is reduced by 44%,and it has a broad application prospect in compact wireless communication equipment.
