介绍了一种经过复杂变形的槽螺旋天线，该天线具有超宽的频带。与普通平面螺旋天线相比，该天线减小了天线尺寸，简化了天线结构。仿真和实测结果显示天线具有良好的圆极化和宽频带特性，在频段0．75GHz-8GHz（10．7：1）上实测反射损耗小于-10dB，同时在频段0．95～8GHz上有较好的圆极化辐射特性。

英文摘要：

This paper introduces a complex deforming slot spiral antenna with super-wide bandwidth. Comparing with the conventional spiral antenna, the designed antenna size is greatly reduced and the antenna structure is simplified. Simulated and experimental results show that the proposed antenna has the characteristics of good circular polarization and wide bandwidth. Its measured return loss is less than - 10dB in the range 0. 75 to 8GHz （ 10.7：1 ）and it is of the good circular polarization in the range 0. 95 to 8GHz.
