摘　　要：提出了一种宽带螺旋平面天线的设计。采用共平面波导的方式绕成天线,该方法使得天线和馈电网络在同一平面上,可以利用印刷电路板技术制作。通过软件仿真和实际测试显示:该天线具有良好的圆极化和宽频带特性,在频段2.5 GHz^9 GHz上实测反射损耗小于-10 d B。该天线制作简单、平面化面积小、具有很高的应用价值。A spiral antenna with bandwidth is introduced. An external feeding is applied to an elevated coplanar waveguide winding spiral antenna. The whole structure is completely planar and can be easily realized by printed circuit technology. Simulated and experimented results show that the antenna has characteristics of good circular polarization and wide bandwidth. Its measured reflecting loss is less than-10 d B in the range 2. 5 GHz to 9 GHz.
